Yes!

Veryy nice setup JTP!


So for your front, you are running -4.5 camber? Mine is maxing out at 3.5 after shaving down the camber plates. Time to do the moar front camber mod you showed me a while back.. I Still need the rear individual camber links.. I need that zero rear camber!

Engine build in the process right now for more power..


Oh and congrats on becoming the new moderator!

don't do it!! as long as stock is working well ( and if not, make it work well) leave it.. i guess in the end it's up to you, but FC hand brakes should work just fine as long as you're input thru the steering wheel is aggressive enough to initiate the drift.

let me ask you this... what's your reasoning for wanting a hydro hand brake?

correct, you want more negative camber for better contact patch "at" angle. you can see the tire is fairly flat, giving a better contact patch to the pavement..

Attachment 710939

sunburn, i don't mean to use this pic as an example, but it's the most convenient pic to compare to..
notice how much "flop" the front wheel has "at" angle... i would suggest adding more static negative camber to correct this. There is other ways of going about it, namely adjusting caster, but stock caster works just fine with other corrections in alignment settings.

That is soooooooo much angle. I am jealous, haha.

What contributes to your ability to have good rear traction? Lots of toe in, zero rear camber, soft rear springs, and a properly set up pinion angle? Is there anything else? Not that I need rear grip... I'm just curious.

you're pretty much on the money.. everything you mentioned adds to rear traction, but the right amount of everything, not too much, not too little.

too much toe in will make the car unstable at angle, wanting to make it go straight very easily off gas.
close to zero rear camber and somewhat large tires adds to it, obviously putting down more rubber to the pavement will always give more traction.
pinion angle is important, but not as much as basic alignment settings, or at least you shouldn't be worried about it, since that can also cause some other issues if not set right.
fairly soft springs and soft suspension settings in the rear also aid to making the rear sit and grabbing traction.
the "myth" of making the car stiff to drift definitely isn't correct, well not it my book... i like to have the rear suspension move and work to get grip, this also promotes more throttle input during drift, which is always exciting.
and one final note... try taking off your sway bars... but only at the track you need them for daily driving... otherwise things can get loose at higher speeds..

Because I might have to hack up the trans tunnel where the E-brake is to fit the trans... I'm going to try to come up with a cleaver way to still use the stock e brake.

I need camber and caster in the front bad. In that pic above I have my camber settings maxed negative.

i'm sure you'll figure something out if you're doing all the fab work..

Yeah I'm doing the work... I'm pretty crafty :lol:

BTW.

Did you solid mount your diff?

This thread is going to be interesting. Hopefully I can provide some input when my vert is ready.

Since I daily the car, I've always run pretty factory stuff.

-3 front camber, -3 rear camber, random pinion angle, zero toe all around. I always run sway bars too. I will try a setup closer to your next season, if I can afford the engine change like I hope to. Otherwise it's 215 front 205 rear with 70psi in them again for next year. :D

yes...

I drive my car to the track and on the HWY it is pretty loose without the rear sway.

USS CJ Dec 10, 2009 02:51 PM

Awesome thread. Its good to see somebody who really knows drift set up make one.

My FC is -3ish front camber, ~0 rear camber
Toe- i have no idea.
Stance GR+ medium stiff in front and about 3 clicks from full soft in the rear
no swaybars- awesome and simple
JTP knuckles- magic
ATS Deftforce LSD

I love the shit out of my car, its got loads of grip and angle and its super predictable and consistent. I deff have justin to thank for why my car is so fun to drive now.

sounds like a pretty good n/a setup.. can't dial too much grip in, due to the amount of power you're driving with...

With my car I picked up a tonne of rear traction going from 6kg to 8kg (no sway bar) maybe to do with too much camber gain when it was softer? or perhaps I had too much camber to begin with (2 degrees). Was night and day. 1.5mm toe in helped too.

sytfu_fc3s Dec 10, 2009 03:35 PM

this thread is awsome.... definitely something that is needed.

my setup is jic flt-a2's 8k f 7k r.

dont know my camber, but the rear is more than the front.

stock brakes ss lines, hawk blue front pads hawk hp+ rear pads. slotted rotors.

i used to have a hell of a time on transitions, and this is making more sense now that i am reading more of you guys setups.

honestly, i know i am about to sound like a dork.. but i am about to try these setups on turismo right now... with the steering wheel that is.

I would look at something more along the lines of bottoming out your susp. on corner load(without a swaybar to transfer some load) which would give you an infinite springrate... Especially if it is under acceleration, putting more weight onto that rear/outside wheel. The higher springrate might be keeping you from this, and keeping your suspension moving the way it should.

The camber could also come into play...

JebusFC Dec 10, 2009 03:58 PM

Thats a really good point!, probaly was bottoming out, never really checked but it was pretty unpredictable at times. Something to look at for other dudes with low cars and 6kg no sway bar!

Really dumb question... How are you running a locked diff? Are you using an NA pumpkin? If you're using a turbo housing/gear etc... how are you doing that? Did you weld a torsen together or something?

JebusFC Dec 10, 2009 04:49 PM

To be honest dude, not sure. Its all turbo stuff. I just found a diff that was local and open head. I think some of our turbo 5 speed came open head. But all our turbo auto's are LSD. Kinda Weird.

ilia Dec 10, 2009 06:09 PM

Weird... I wonder if it's the big ring gear or the small ring gear. What I'm trying to find out is if the small NA differential/axles will work with a turbo motor. I'm broke and I want to keep my welded 4.30 if possible.
