Hi Everyone,

 

I'm experimenting with different alignment specs. and wanted to know what some of you guys have done.

 

If you could provide me with the following:

 

1. front/rear camber

2. front/rear toe

3. caster

4. your rim size/tire size

5. v8/L6/?

6. ecentric cam bushings? type? material?

7. sway bars? adjustable?

 

Because of my super wide rims and tires, 16x10 front, 16x13 rear I have to be much more conservative with alignment specs.

My car is EXTREMELY sensative to bumpsteer.

When I ran 15X8s and competed in AutoX I ran the following:

1.5 Neg. Camber front Zero Tow

.75 Neg. Camber Rear Zero Tow

5 degrees Positive Caster with Aluminum shims

I used the adjustable bsuhings in the rear and an adjustable control arm up front. Tires were 225-50-15 up front and a 265-50-15 out back. I used this with a modified L6, but also ran the same setup with my current V8 project on the street, except for the caster, only ran 3 degrees positive caster.

 

My current setup allows for caster setup with our adjustable TC rods to well over 12 degrees positive caster, and the newer design adjustable control arms for my car. I also have done the bump steer mod and I use camber plates in the rear, and I'm in the middle of designing my own Camber plates for the front. Coil overs and Tokico Premiums are being used at all corners. New wheels and tires are:

17X9 at all corners with a 255-40-17 up front and a 275-40-17 out back.

Mike,

 

Where did you get the adjustable bushings for the rear toe? or did you have something custom?

My car has about .65 degree on each side and that's probably too much for my wide tires. I want to get it down to zero like you.

Hoover,

I used those crappy aluminum units sold by VB, MSA, and Arizona Zcar. However, Our custom rear control arms will do away with the need for those aluminum pieces of crap. Hope to have something done by lat spring, early summer. They are basically like the units Simmon made.

Mike,

 

Very cool!

If I don't figure out something by then, I'll check back with you on the lower control arms.

 

My fronts are 2 (maybe a bit more) degree negative camber with rears at 1.7 degree negative camber. I then adjusted my front sway bar and the car handled with a lot of oversteer. It was kind of fun to have such quick steering, but I had to be really careful negotiating short turngs. Before this, the car snow plowed itself through large banking turns.

Taking away some of my camber will help a lot with the oversteer. I'll also adjust my rear sway bar and see what happens.

 

I know the Scarab conversions are a bad design (that's what I have). But my wide rims sure do compensate a lot. I can't begin to imagine how the car would handle if I set the engine back and lower it about 2".... smile.gif
