I read somewhere and cant find the mod where the 18mm and 9mm bushings are swapped? on the upper control arms to gain camber for better cornering.
Anyone know this mod, and have pictures? Sailor proof pics , so I can do it. Thanks, Steve

PM me your email address. I have got some pictures of Gene's setup. His handle here is Jacki&GeneZ16.

We swapped the inside and outside oval washer thingys to get more neg camber. Is that what you mean? I also knew a guy that had shaved the washers down.

We also shimmed the rear of the K member in with the shimms that go in the stock control arms.

Does that sound right? It's been a few years.

I am not sure, But I heard you can swap the bishings up top on the upper control arms. SOmething to do with the front rear bolts, and two bishings. Makes a big difference on camber availablity.

Is this the modification for the spacers? They talk of caster being increased, but not camber.

They moved the spacers front to rear to change the caster (the spacers are different thicknesses). This is not really needed IMO on later ('88 & up) C4s.

Machining both spacers equally will help with camber. I had mine machined .120" thinner. In conjunction with my installation of Global West del-a-lum bushings, I now have nearly -2.0* of camber up front and my caster is still >6*

After reading the article etc, I realized it wouldnt be a benifit for my 93. I have about 5-6 degrees caster already as it is lowered and this caused the caster to go up.
But for extra camber, the machining seems reasonable. But I still have allot of shims I can take out in there for additional camber if needed.

Steve,
Are you road racing, auto-X-ing or just driving on the road? The reason I ask is, if being used to SCCA auto X in stock or SP, then the bushings must remain in their stock locations and in their original thickness. If the car is not being used for this, then I would recommend doing it as it will make the the car more stable. I have tried it on the track and it really made the car better at high speeds.

Mostly street but autocrossing. My Vette is lowered and am using the VB&P advanced street alignment. I do have quite a bit of caster do to lowering anyways. But camber mods are worth it apparently on the C4.
