Godsquadmandrake is either not smart enough to understand my statement or is describing how he feels.

I'm about ready to purchase some stage 3's. Anyone heard from Cam on the updated versions?

RotaryRX-007

Looked at his site last night and none of the coilovers are listed anymore. Looks like the site was/is being updated a little but I was surprised not to see them listed at all. Call him to get it straight from the horses mouth.

Since everyone had their Pettit coilovers for quite some time I am bringing this thread back to life. What are your preferred settings for street on Trak Pro Stage 2 coilovers?

My car understeers a little, and although it's mainly because of the staggered wheel/tyre setup, just want to know at what settings you found the car most neutral and smooth.

At the moment my car is 8 or 10 clicks from the softest on both sides and feels a little hard on street but not hard enough to stop occassional front tyre rub on hard turns...

What kind of stagger?

ALPSTA

255/35 and 265/35 but also 10mm spacers at the back.

I emailed Pettit Racing a while back about these coilovers and their no longer selling these. He claimed they were selling the BC Racing coilovers.

Would Pettit still be able to source new springs for those intested in increasing the spring rate?

My stage 3 (12k 10k) setup is feeling soft now and would like to up to 14k/12k. I emailed pettit almost a year ago and havnt heard back.

Also, I am beginning not to feel a big difference when changing the shock settings. Its almost gotten to the point where I dont even know if clockwise stiffens and counter clockwise softens. I run full stiff (clockwise)

Here is a pictures of my car leaning with the pettit coilovers. 265/35/18 front 275/35/18 rear hankook rs3 street tires. Stock sway bars. Balance is nice, just a bit soft.

First I would like to say thank you for all of the feedback and work you guys have done here.

Did you ever finish rebuilding the Konis and running their sleeves?

Better results then the GCs?

Right now I am running racing beat springs and what look like oem R1 shocks. From what I have read these springs will give me clearance issues with the wheel and tire setup I want to run.

jkstill

iTrader: (11)

Yes, that was done early last year.

I like the results, the car feels more stable, especially when cornering hard.

One thing I might change, is to increase the rear spring rate.

The springs are 5" Hyperco, and they bottom out in spots on some autox course.

Haven't yet tried them on a track, but don't expect issues there, as I don't drive as hard on track as on an autox course.

There were several changes here, so they all contributed:
* Tripoint upper shock mounts
* Springs cannot bend under compression
* New spring rates
* Shocks rebuilt

StanBo_IFX

Thanks for the info.

What are you using for bump-stops?

Any reason why you went with the Tripoint upper shock mounts over the oem rubber?

I am researching your setup now trying to figure out the part numbers to build it. I have seen some shops that build custom one offs. I don't think I am at that level of driving. Shoot I have only had the damn car on the road twice. I also know I have to do my diff bushings before I take do anything else serious.

I am all for the GC/Yellows or Tein Flex. Hammering the two out now pros vs cons.

Thanks for letting me pick your brain.

Right now I am trying to find the body specs for the 8041 shocks. I take it these were the ones you had rebuilt correct?

If you had a shop build the setup for you and wouldn't mind sharing the info it would be appreciated.

Either way thanks for another option.

Fatcat Motorsports - I don't recall exactly which ones at the moment, and can't seem to find the order for those.

Trying to eliminate as much unwanted flex in the suspension as possible.
I am more interested in control than a smooth ride.

Here is the full list of sleeves and hats from Koni
Koni Racing Shock Sleeves

Part # for the kit I bought - 4 of these were about $330.00
KON80.0000.1 42mm ID Coil Over Kit - 25mm upper spring perch

Specs for the shocks:

Front:
2 Koni 8041-1169
New Spring Rate: 900 lbs

Thanks for the quick reply!

I have been on a tear and got a bunch of the part numbers hammered down. With that comes new questions.

KON80.0000.1 looks like the cat's meow. I found part numbers:

Threaded Spring Perch Sleeves - 42mm 80.0000.0005
Threaded Spring Perch Sleeves - 42mm Lower Perch 80.0000.0006

I also found the springs from Hyperco as:

5" / 2.25" inner diameter / 400lbs Spring 5A0400
5" / 2.25" inner diameter / 450lbs Spring 5A0450

I figure they aren't the 432F / 378R setup that Howard suggested but they should work seeing that instead of a 54lbs difference there is a 50lbs.

Didn't get to ask you what inner diameter spring you ran?

Shoot with the kit part number you gave me it looks like I will be doing this instead of the flex or GC. I will give Truechoice a call tomorrow to see what it will take to make this all happen. I like the fact that I can grow with this setup.

Funny I was on Fat Cat's site earlier today. I thought his setup (awesome as it is) would be a little bit out of my skill range.

Come to think of it the 300+ whp the car makes now is feisty enough to get me in serious trouble lol.

Thanks again it is appreciated!

Hey I say we name this brew after you:

What you may not have noticed is that kit includes a 25mm upper spring perch.
This is the part that keeps the springs from bending under load.

This will require a spacer from the top of the perch to shock tower mount.
The upper shock mounts from Tripoint include that spacer.

2.25 is required for the Koni sleeves.

You're welcome.

BTW, if you get Koni's rebuilt, they will cut new grooves in the schocks for the sleeves.

You may want to them to cut an extra set another .5 - .75 inch lower for future changes.

I neglected to do so, and had to cut a new set of grooves myself.

Fortunately the shocks fit in my lathe.

StanBo_IFX

Yes! That is the next part I was going to try to find lol. I was going off pictures I found online and old threads on Honda-Tech.

There is a reason builders get paid what they know. They have already been thru this lol.

Hmmm valid point. I will talk to True Choice tomorrow and see if they can figure a spacer to work with the oem hats. That will give the guys that want the rubber vs the metal hat an option.

Sweet and this is what will help clear the wheels and tires I want to run. I am copying another setup I dug here.



18x10.5 7.75" Backspace Classic (Bryan Downs) w/ 285/30ZR18 HTR Z II (Howard Coleman calculation verified 107% over wheel width).



Lol no one likes doing things three times. I have done stuff enough where skipping one or two steps helps.

StanBo_IFX

Thanks I will add that note to the spreadsheet as well.

I do see myself doing a trackday and some autox with this car. I planned to do way more with my S14. I can get replacement chassis for cheaper then the RX7.

StanBo_IFX

I don't know what you are running for a spanner wrench but I found a mention of this one here on Honda-Tech.

I was figuring I could wing it until they get in. I have a bunch of spanner wrenches from old setups in my toolbox.

My FD has 18x10 with 7.5" backspace, running 285/30/18 Hoosier A6.

Hoosiers run a little wide.

It was necessary to install aftermarket trailing arms and 5mm spacers so the tires didn't rub too much on the inside.

So effectively I am running 7.25" backspace with the spacer.

Oh, and 5 lb sledge had to be employed on a couple spots on the inner fender at the front of the wheel well.

I would be surprised if 7.75" backspace didn't have rubbing issues with those tires.

Same size is being used on the front, and clearance on the fronts is mostly fine.

After catching a front tire on one of the plastic mud guards, I removed the mud guards, and used a hammer and dolly to bend the lower fender lips back out of the way - no clearance issues now.

StanBo_IFX

Funny you mention that. Bryan runs a .25" spacer in the rear for clearance/flush fit to the fender. Sounds like the same track you took.

I was planning on having my bodyshop buddy roll my fenders.

What trailing arms are you running? It seems many of the threads I find on them are on parts that are no longer sold or Megan racing.

jkstill

iTrader: (11)

Mine are Improved Racing, and as you found, they are no longer available.

If you need some modified trailing arms, just request some in the FD parts section.

If you don't need them, don't bother - the stock FD trailing arms are pretty good, and lighter than after market.

The stock trailing arms are just ridiculously light.

StanBo_IFX

Bazinga! I found a manufacturer that might still sell their rear trailing arms. It also happens to be one that I would trust.

Cusco 442 474 T $340 or so (ouch).

I figure I get the bushings for the diff because they are needed no matter what. Mine are shot. I can then get the wheels and tires and your koni/hyperco brew.

If they wheels don't fit because of the arms then I will run out and grab a pair of Cuscos.

Like you said if I don't need them then they will get some new bushings and call it a day.

Eye candy:





Also a nifty chart showing all of the bushings sold by powerflex.

Does anybody know if PETTIT is still servicing the track pro coilovers? Rebuild, new springs, boots, etc. I have emailed/called and have not been lucky so far. I dont have time to sit around and keep trying unfortunately.

It will be quite unfortunate if these coilovers are no longer serviced in the states.

Cam and I were talking Friday about stuff, and I brought up the Trak Pro question.
He said that even though they are not listed on his site, he still sells them. He has some other specialized items that are not listed.
