I've got SuperPro bushings at both locations in the front control arm. The rear bushing in the front control arm is the offset SuperPro Duroball. I have a thread in this forum describing my experiences with these bushings. Vehicle rake is an important part to the caster gain. Too many people go for the raked look, and a lot of caster is lost. I'm sure its easy to give up 0.5 deg of caster with the classic raked Evo look. My Evo has around 1.25" gap between tire and fender at front and ≤0.25" gap at the rear. Its not a bad-*** look, but I get my caster.

Same here. Looks like crap, but works well. I have Vorshlag Camber plates, Perrin PSRS, and 13mm of rake. Am I wrong in remembering my alignment specs showed between 7-7.5* of caster? I can dig out the paperwork but am just curious if that sounds right. I remember thinking "whaaa?" when I got the final measurement Old pic, but alignment is the same:

I don't think 7 is unrealistic. I'm at 5.5 with SSB tophats and custom LCA bushings (have about 1.5mm more offset than the PSRS) and am about 1" of rake.

Stock is around 3.5deg, offset bushings tend to add about 1deg, my 20mm offset tophats add 1.65 deg, that puts you at 6.15-ish. Then you an add some car variance, maybe where you have the subframe positioned, and rake. I could see +/- 0.5deg from there for sure.

Hey man!
So what height from center of axle to fender are you running normally?
What Mrfred (I think it was him) said his was like 13.5 front and like 12 rear which seems like it would be slammed to me. I'm not racing but I would like to get that rake to be ideal just to say my setup is good for track lol

I'm not sure. I measured from rails on the bottom of the car. Front and rear fender openings differ, so it would be pretty complicated for me to do all that math. I'm to lazy for that. Though not having to lay on the ground would be nice LOL

I'm at 13.75" front and 12.75" rear. Its a very streetable height. I still have to be a bit careful on very steep transitions, but generally I can negotiate driveways normally.

What is the difference in fender height, front to rear? Assuming nothing has been pulled, of course. I'd like to subtract that number +13mm to get my rake. I really don't like laying on the floor, if I don't have to

Front fender is 0.75" higher than the rear. I guess the front wheel looses about 0.25" due to more weight on the front tires. Fenders are completely stock. I can measure the height under the skirt if you want.

Oh, no. That's perfect, thank you. So then, I can measure the fenders, and look for a 0.50" difference. All without laying on the ground. I can then confirm from under the car, after I get it where I want. I already have a homemade plumb bob that will work great for this.

Its fine to use them. I have them on my Evo too. They add a little more correction.
