More camber front - Comptech camber kit ?

[asylum]

Looking at my front tires wear, I need more camber. ~3.5 at the rear seems ok but with 2.0 - 2.5 front it is not enough.

Can I still find a Comptech camber kit ? Where ? Do someone has a used one for me ? Does another company make an equivalent ?

If not, of what does this kit consist ? Would it be possible to make a copy if we get the quotes ?

Unfortunately this kit is to reduce the negative camber. Not to missunderstand, I need more negative camber.

You can still get the Comptech bushings to allow you to get up to -4 degrees in the front.

You can order them through Bob @ Driving Ambitions (916)861-0032. They just installed mine with -3.5 camber in the front. Now no more fender rubbing issues with the larger front tires.

If you are looking at reducing inside edge wear more camber is not going to help. Most camber kits are for racing where more neg camber helps the tire stay in contact with the road in hard cornering.

No I have to much outside wear with ~-2.0° camber. I need 3° or perhaps more.

I think something is getting lost in translation, I have never heard of problem with to much wear on the outside of the front tires. I think you need to get the car on an alinement rack and see if it can even be adjusted to spec.

i believe the OP's car is a hardcore track car and he wants more negative camber in the front than the stock suspension geometry allows.

 

[Briank]

Yes I am finelly getting that LOL, yes he is having issues with rolling the tire with cornering loads which is more of a tire, air pressure and driving style problem then alinement issue. I track my car with stock alinement spec and OEM Yokos and have no roll over wear problem.

I run slicks :wink: Shure if I drive slowlier in the corners, I will get an even wear. But this is not my goal :tongue:

You are talking about street driving with excessive camber wearing the inside of the tire. That is definitely not a problem on the track.

Ah, Brian you are not driving fast enough.... If you are pushing hard, I mean real hard, even maxing out the NSX's camber will not prevent the tire from rolling over. Ken Sax runs stock alignment specs but then again, he drives like a Grandma and I don't have a problem lapping Ken twice during a 20 minute session.

Street tires start howling when you roll them over.... if your tires are howling then they are starting to roll over on the OUTSIDE edge.

I just corded the outside edge of my left front Nitto NT01 in 4 track days with almost full tread on the inside. I have my camber maxed out at -1.7 degrees, type R sway and JRZ dampers 600 lb/500lb. The Comptech camber bushings to get -3 deg is going on tomorrow.

Brian, when you are pushing the car hard enough to chase down and pass Porsche 911 GT3s then you too will roll over the front tires. :tongue:

CL before you blame your lack of - camber on your front tire outer wear,,check to make sure your front susp bushings and all component arms are stuck together tightly.I had outer wear issues as well maxed out with stock susp and I had loose components:frown:

-This will better help us know what your setup is and possibly point out a problem. At a minimum, we will know what you are running to give you more relevant comments and advice.

doc... I was actually running with a mystery alignment.:tongue: I swapped springs and readjusted the ride height by more or less guessing and a ruler. The car ran straight and my chassis guy couldn't get me in until tomorrow so I didn't want to pay for a corner balance and alignment from the place up the street before hand as it was going to have to be done again after putting in the bushings.

I have thee goals for putting in the camber bushings and running -3 deg.
1. Tuck in my 235/40/17s so they don't rub (not talking about the inside at full lock).
2. ^ be able to lower the car more than the 1/2" I am running to avoid rubbing the fender liner top.
3. Some manly camber to get the Nittos to bite and reduce my outside tire wear.

If there is anything loose, my chassis guy will find it when doing the bushings. He's one of the best ~ except that he is gone Thur - Sun working for an ALMS team.

For the spies :biggrin:

Front Camber: ~-2° (outside tire wear)
Front Toe: ~-2 mm each side
Front caster : ~9°
Rear Camber: ~-3.5 ° (even tire wear)
Rear Toe: ~+3.0 mm each side

Front & Rear spring rates: Tein Flex (10/12 kg)
Dali track sways, middle hole front, full soft rear.

240/610-17 Yokohama A005 slicks on 17x8 +40
260/640-17 Yokohama A005 slicks on 17x9 +45

Power level: 300-310 bhp
Weight: ??? (1200 kg ???)


The car feels really perfect. Very neutral and stable. Just the outside front tire wear makes me wish a little more negative camber.

Does the car ever have any oversteer? Is it true neutrality (on the edge of oversteer) or is it a light/comfortable understeer?

Would you say the understeer is worse on entry, mid-corner, or exit?

You do have a lot of rear camber relative to front (-3.5 to -2*). Decreasing the rear to -3* should help.

Softening the front bar by one hole, might help as well (pending response on first 2 questions.

Reducing front toe to 1mm should help slightly with overall wear and might improve turn-in.

What tire pressure are you running front and rear?

Also those tires do like 2.5-3.5* of camber.

I would say that. Very predictable thought.

Would you say the understeer is worse on entry, mid-corner, or exit?

No understeer at entry and the car is very stable when tail braking (except if I go to far :biggrin. Perhaps a very little bit at exit.

I have perhaps -3°. Would have to check again when I do the front camber bushings.

This is an option as well as working with the stiffness of the Tein. Trying to have the best settings for each track I go. I have some work left :wink:

What tire pressure are you running front and rear?

I did my best lap time at the end of the day when I tried to reduce the pressure to 1.6 front / 1.7 bars rear (23/25 psi).
