I finally got a chance to drive my car today with the new Pettit Trak Pro Stage IIs. The ride is great, first took it out on the softest setting and found it to be too soft for my preference. I'm coming from 16kg f/r and am not used to any body roll. So, I moved the dampners 12 clicks--right in the middle on all 4 corners and that's how I've been driving my car ever since. Looking forward to getting some wide wheels and sticky rubber to enhance the handling even more. They're still settling, but at the last adjustment, the fronts were set at 25" and the rears at 25.5". Eventually I would like to get the rear down to equal the fronts...

Is there room to lower the car more, say 24-24-1/2 inches?

Rice Hata

I'm not sure if you can (or should) lower these coilovers to 24-24.5". You would be tucking a good amount of tire and rubbing your fender lines raw at that point. Not to mention bottoming out the suspension. I would call or email Cam if you're serious about dropping the car that low.

at that ride height you may not be able to dial back out the negative camber to a street friendly setting.

That is where my car is sitting at right now on my Stances with rolled fenders I have no issue with rubbing the fenders. I was just not sure if your height of 25" still had another in of lowering. I am just sick of the pillow *****, I have talked to Cam about seeing if I can purchase a set of upper mounts but waiting to hear back from him. If that falls thru I will just have try to build something myself, or sell them and get the Trackpros...

does anyone have any idea when these are coming off backorder?

Hey eyecandy,

If you want to get rid of the pillowballs I can request them from Stance for you. When did you buy your coils?

Please don't hesitate to email me sales@autornd.com.

As for Stance I am already placing an order with Stance for the Rigid Bushing uppermount and the rubber isolator above the spring. So we should have that stuff handled for all the new FD applications. Might take a couple months before it gets here.

Thanks, Rishie

"does anyone have any idea when these are coming off backorder?"

Cam called today to tell me he was shipping my Stage 3 set of Trak Pros. i have a few items to finish before getting on the road but am really motivated.

i mentioned that someone on the thread said they were back ordered but Cam said they are available.

After reading what you all had to say about these and speaking with a few other guys about my FD, I decided to call Cam about the stage III's for my car.
I took it to Sebring a few weeks ago and the ride was horrible. The previous owner put typical soft lowering springs on the car and even with the Tokicos turned all the way up the car was scrubbing around every corner.
I have built the car with road course in mind, and occasional street driving as well. ( It's a great looking car, why not take it to dinner sometimes?) And with all the mods and 400+ WHP i'm not likely to drive it conservatively even on the street. Too many fanboys with supp'd up civics that need to be taught what 1.3L really runs like.
With all that in mind I made the call and explained the car and my heavy foot and Cam suggested a new prototype "Comp" series racing coilover that he has been testing for about 6 months. I don't have any specs yet but he said he would sell me a pair to try out. They are about double the $$ of teh Stage III's but he says they will blow away any of the Olin's or Tien's and after what everyone is saying about the trakpro's I think i'm gong to have to jump on the oportunity.
I will Let you know when they arrive and I'll post pics and stats of everything.
Doesn't matter how fast it goes or how well it stops if it corners like a model T!

So were the stage III's terrible or was it only because of the springs you had on them?

BTW nice clip of the pass on the NSX.

He didn't have stage III's, as he posted he had Tokicos with lowering springs. He call Cam about the stage IIIs and is going to test out the new "Comps".

note the lower picture in post 63.

this picture clearly illustrates why the FD is a potential ruler of the roadcourse.

the car is rolling 3 degrees

the crucial outside front wheel has moved 2.5 inches into the wheel well (bump).

BUT LOOK AT THE CAMBER!!!

it is a degree or two negative which is perfect. there is nothing wrong w a touch of roll if the negative camber gain makes up for the roll.

that picture sends a funny feeling up my leg.

BTW, my stage 3 Trak Pros should arrive any day. i will also be comparing them to the Comp setup and will also evaluate the stage one.

i will be shuffling springs too.

ahh got it...my comprehension skills took a holiday apparently. Look forward to the review of the test stuff from cam and the stage IIIs.

My super secret "comp" coilovers will be here today. Spring rate is 15 f/12 r so We will see. Cam says after his tests that these rates allow the use of no rear sway bar and only the rear strut brace to keep the car pretty stable on just about any surface with minimal roll.
He also said they are working on an adjustable rear sway that can be easily disconnected, for use on extremely smooth tracks/roads where these high rates may tend to push the rear around.
All speculation until the UPS box arrives, (tracking puts it here by 10am so I'm like a kid waiting for Christmas morning)Then I will get tehm on the car and start doing some road tests.
We have a few abandoned/unfinished neighborhoods around here that make pretty nice minitracks for testing. only get a few laps in though before someone nearby see us and calls PD.
I'll keep you posted and I'll post results/pics.

just received my Trak Pro Stage 3 coil overs. if i get a chance i will remove the upper mount and take a pic of the trick rubber load absorber. i need to remove the shock rod rubber anyway so i can add a tie wrap. there has been lots of spring rate talk, and rightly so because it is the most important coil over feature. ontrack it all gets down to travel. the FD shock absorber (and spring) moves .605 of an inch for each inch of wheel travel in the front and .68 in the rear. you want approx 2 inches of wheel travel so that works out to approx 1.25 on the front shock rod and 1.35 in the rear max. you DO want roll or travel.

there are two ontrack considerations as to spring rate:

roll couple front and rear.. really over and understeer... can be effected by swaybars, static weight distribution and springs.

travel.... contrary to many's conclusions...... you want some. so the tie wraps tell the tale and on they go.

the units weigh 11.6 pounds each, front and rear.








didn't get a chance to dust these suckers after unpacking them. sorry.





i like the way they lightened the bottom of the shock body



it will be a couple of weeks before they get evaluated. i am close to having my T56 working in the car, i have to reassemble my motor, fab a downpipe for my new GT4094r and CPR manifold, install the brake bias bar i bought yesterday from Damian and maybe put the M2 roll bar in the car. it will then be off to Blackhawk where you go if you want to dial in the chassis. i do have a GPS PerformanceBox so i will have all the laptimes, all the Gs pulled and actually be able to post a lapmap etc. i would also like to take an assortment of springs along. it will be a busy day. fun too.

So mine came in today and I was excited to post pics but they look just like Howards so you already know what they look like.

I will do my best to have them installed by saturday. Wife/job willing!

I will let you know how they do on the street anyway. and I will have install pics as I go. I won't have any fancy lap times or tracking maps, I'll leave that to the profesional (Howard), but I will be able to put them through the paces around town and on some back road twisties.

I'll keep you posted.

Hi Howard,

Great post, as usual.

You chose the 12kg/10kg Stage III kit over the 10kg/8kg Stage II kit. Any insight?

gracer7-rx7

iTrader: (16)

What kind of shocks are those?
Rebuildable?

Howard Coleman

"You chose the 12kg/10kg Stage III kit over the 10kg/8kg Stage II kit. Any insight?"

the plan is for me to test all of the different packages. i chose Stage 3 initially. Stage 3 comes w the 12/10 springs. as i have previously posted springs are going to be a project so we will see what setups work best for various applications. we will be shuffling springs.

yes they are rebuildable.

Are they rebuildable or replaceable damper units? Meaning can they be custom valved stateside? Anybody find out the cost of rebuilding or replacing the damper unit?

Any new updates on the stage II kit? My car sits at 27" front and 27.5" rear. Maybe it's got the Colorado lift kit for winter snow...

What was you ride height stock? I'm afraid these coilovers won't get me down to 25" all around.

Rice Hata

I just returned from 2 weeks of business trips, so I haven't had time to play around with them too much. My car had Tein Circuit Master Type RE coilovers on when I bought it (16kg f/r) and the car sat around 25" in the front and slightly higher in the rear. I can't tell you how my car was with stock suspension..

If you look at the description on Pettit's site, I believe it says these will lower your car up to 2". That should get you down where you need to be-- snow plow style. Might test the car with the dampners as stiff as possible to see the difference between 12 and 24 clicks.

I also purchased a set of 18x10 CCW Classics and some 285/30 Sumitomo HTR ZIIIs which need to be balanced and installed. I won't mess with the ride height again until I get these on- probably next weekend.



Also, in regards to rebuilding the coilovers- when I spoke to Cam prior to ordering, he said he was looking into purchasing a shock dyno. The coilovers are made in Japan to his specs and I believe he mentioned a place in the U.S. that will rebuild them until he gets the shock dyno. This was a few weeks ago so things might have changed. Give Cam a call or shoot him an email if you have any questions.

I spent friday night in my garage putting the Comp series on the car.
The new coilovers were much shorter than the Eibach/ tokico combination so I was a little afraid that when we put the wheels back on and lowered the car it was going to land on the garage floor.
That couldn't be farther from the truth. The came set at the perfect ride height for the FD.

I have Volk racing RE-30 17's with Toyo Proxes 235/45 zr17 front and 265/40 zr 17 rear and the car is sitting 26" front and rear to the center of the wheel well.
this stance places the rear trail arms parallel with ground, as Cam stated it should be. I want to have the car aligned before I hit the track again, but the ride is unbeleivable.

I took the car to some of the roads that I usually run to give it a test. In corners where the old setup used to scrub and bottom at 35mph it now runs through comfortably at 50mph.
I can hold corners that I used to slide through and the body roll is nearly gone at the softest setting.
I'm not sure how they will compare to the stage II or III setups as the spring rate on these much higher, 15/12 f/r but even at that stiffness the car drives like a new machine.

I will have to get it to a controlled area where I can mark lap times and test skid vs stiffness, but so far for heavy footed street use, these things rock.

Thanks to Cam and the folks at Pettit for the design and help with everything.

I see the Trak Pro Stage I, II, and III on their website. What is the Comp series?
