Possible to flip the front LCA bushing? on C5
My rear front LCA bushing shoulder was chewed up due to braking forces. I replaced with some cheap prothane poly but they are NOT any better and front LCA is VERY close to metal on metal, plus I'm loosing a lot of caster.
Measuring the space on each side of the bushings, seems NOT possible to flip the front bushing due to the shoulder thickness. Have other people done this? I'd hate to get everything apart and fail.

Bought a c6z now.

Yeah, I flipped upper long ago. Not sure if this was gradual or more sudden... surprising I missed it if been like this for awhile. I'm leaning toward Delrin replacement on just these arms for now.

Go with a good set of replacement bushings. Flipping bushings really won't work. The early C5 LCAs seemed to be more susceptible to bushing slip than the later ones. In 6 years the ones on my 97 were metal to metal running about 5 track days per year and a number of autocrosses per year. The 03 Z went 6 years on the stock bushings with no slippage doing 10 track days per year while running much lower lap times and doing more autocrosses.

Agree with Bill, the latest stock c5z rubber ones appear to be a better quality and/or life. Keep in mind if you do poly or delrin, and this from my personal experience, those are nice on a smooth track/autox venue if you can put up with the extra nvh on the street. On a rough autox lot (think SD) you will wish you had the rubber back. Skipping the car like a stone on a pond from peak to peak of the bumps/patches/grates/etc. does not result in a fast lap time although your car control skills will get a useful workout.
My new to me c6z is a smooth operator (with stock rubber bushings) compared to my c5z with t1 springs and Pfadt bushings. On track my c5z is on rails. But I have no intention of messing with the rubber bushing ca's on the c6z.

Borg sells individual Delrin bushings... I ended up ordering only the front LCA, which if pieced together is only slightly higher than the full set. A great deal I think!
