Quick help please installing Koni/Eibach/GC now. Cutting bumpstops?
I have the car up on jackstands and need some quick advice. Ground Control sent me shocks over a month ago (wrong rears) so they sent the right ones on the 88 CRX. Now though I can't find the instructions on install. I know somewhere it said to cut a bump stop (maybe on the front). Anybody know what is recommended? Which part of the bumpstop and how much? Am I right? TIA.

Bump stop on your car is a symetrical cylinder about 1.5 inches tall with a slight taper on each end. You can generally pretty safely cut about 1/3 off either end or cut up to half but it leaves you very little crushable room left since the Koni have the steel ring welded to the rod. My suggestion would be to remove between 1/3 and 1/2 and hand the more conservative the better.
While you are at it, take a zip tie and pull it tight around each shock rod and cut the tail off. This is a free travel indicator and if pushed down onto the top of the shock body before a session, will indicate the maximum point of compression the shock saw during the session. Hitting bump, berms, etc. will push it up but generally can help you select your safe ride height for conditions. Coming in and finding the zip tie smashed up to in into the bump rubber is saying that for your spring rate and height, you are using every bit of available travel and could likely use more. Then you could decide to reduce the bump rubber (be careful), raise the ride height or raise the spring rate. Any way, a zip tie is a nearly free indicator and data gathering device.

my instructions that came with my GC's told me to cut the bumpstop in 1/2, use the upper half, and toss the other half.
Catch 22 I would be SOL without the forum. I get my "money's" worth out of it. I took a very conservative 1/3 out of the front bumpstop. Put on brake duct set up today. Tomorrow in goes the Sparco EVO 2 and harness. Got to cut up my dash so it will fit in after my so well received roll cage install. I did my cable to hydro tranny conversion this week (trick billet pieces from Hasport) and now have a ITR USDM tranny (nice ratios) with the JDM final drive 4.875. So I am now "type R" under the hood engine and drivetrain. My brakes still suck even though they were supposedly fixed (they are not). Bleed them and put new rotors and it is still too mushy. Crap. Alignment and brakes Monday.
