Eibach Prokits for P10

[JG20]

I have a few questions for anyone else w/ Prokits on their P10. How much was the drop and how's the ride quality?

Here's my observationsons:

1)front wheel well gap first at approx. one inch (stock wheels and tires, 195/65/14inch), Therefore, approx. one inch drop from stock.
- excellent cornering, hates bumps... bumps got worst
- recently I checked how much suspension travel I had by raising the car, tying a zip tie aound the top of the shock and lowering the car to see where the top of the shock is at rest
- to my surprise, no travel, yes that's right, the zip tie was right against the bumpstop, no wonder it was so bad during bumps
- solution, cut the bumpstops.... last week, I took off about an inch, since the car was was resting on the bumpstops, it ended up even lower (at this point I can barely fit my index finger in the wheel well)
- a test drive yielded significantly better ride quality even though it was lower and the cornering was still great...
- one week later, it seems to keep on sagging, there is now no wheel well gap and I'm pretty sure I'm resting on what's left of the bumpstop now...
- I was thinking, if I can precompress the spring even more like with a spacer between the top hat and top of the spring, the car won't be as low which would give some (better than none) suspention travel until I save enough money to get AGXs (which I think have shortened strut bodies)

Does anybody have an idea as to where I can get this "spacer"?
In the mean time, I will do my own search of materials that I can use.

2)rear wheel well gap approx. 1 1/4 to 1 1/2inch, therefore, the drop is 1/2 to 3/4 inch
- the car always looks like it's going downhill
- the rear has about one inch of suspension travel with uncut bumpstops, which I think is sufficient in the rear.
- I want the rear a bit lower though (about one inch wheel well gap) so it matches the front when I finally get that right.

Should I cut the spring, and how much?
Keep in mind, these are not stock springs so they are stiffer and I will cut the rear bumpstops.
If not, then what should I do?

Thanks in anvance
Joe

P.S. If I have suspention travel problems with prokits (supposedly 1.2 inch drop), imagine how bad Intrax (1.7inch drop) or other super low springs would be. Something to keep in mind for those who are shopping around for springs.

P.S.S. Those few days I had suspention travel in the front felt better than the stock springs. Smoother over bumps but still corners better.

Hmm. I had Prokits with GABs on my P10 and I had about a 1" gap in the front and 1.25" gap in the rear with the same tires as you. I did cut my bumpstops when I installed them but the springs did not "sag" as much as you described. I rode on them for about a year and the gaps pretty much stayed the same. Maybe just cut the bumpstops in the rear first before cutting the spring.

Well I just fixed the front today. I used rubber spacers that placed the spring further down from the top hat. I have a little less than an inch fender gap in the front now but the good news is that I have suspention travel, even if it is only an inch or so.

Tomorrow I tackle the rears. Unlike the fronts, I do have travel in the rear, i.e. its not resting on the bumpstop. I think I'm going to cut half a coil from the softer side of the spring which should lower it a bit and also make it stiffer. I'm also going to cut the bumpstops. I just want the rear to be at the same height as the fronts so if it gets to low, I can add spacers to raise it a bit.

I'm just curious if you assembled the front corretly? Your problems sound weird.

[JG20]

When I replaced the springs, I put everything back the way it was before. I'll check again with the FSM if everything is lined up properly.

On the other hand I have a p10 with intrax springs and kyb GR2 shocks...I run 20540r16s in front and 20550r16s in the back, and so far so good...if i hit a big bump then the back tires (which I believe are the same as the stock diameter) rub the fender....but overall the ride is surprisingly good!

I believe the GR2 shocks are the same as stock. That's a pretty small diameter up front. Did you cut your bumpstops cause if you didn't, I bet your riding on them.
