The bounce isn't terrible when compared to other stiff coilovers. The problem is that it seemed to oscilate more than necessary after a small bump in the road. Over large bumps or rough road it's fine, it's just the little bumps seemed to make the car oscillate once or twice. It didn't bother me until about an hour into a drive. So around town, or on short trips, no big whoop. But after about an hour, say driving to Sacramento or something, I'd start to feel tossed about.

I tried a bunch of things to fix the issue. Initially I thought it was an issue of being over-damped... with the bounce being caused by the tires themselves. I so I went to the stiffer rear springs. It helped the bounce a little, but didn't get rid of it. The nice side effect was that the stiffer rear springs really made the car ride great for autocross. So I stopped trying to dial out the bounce and just lived with it, since I wasn't driving long distance very often.

In hindsight, I think the car is actually over-sprung... which is what normally causes bounce. Some softer springs on the car may actually make it downright comfortable, but I need some stiff rates for the track, so I never tried that route. The JICs use standard 2.5" ID springs, so anything from the Eibach catalog would work, which means you can get a complete set of springs for around $200 IIRC.

Since you're local, if you're interested in buying the coilovers, I'd be happy to help with the install, plus I've got everything to do an alignment in my garage, so you wouldn't need to drop $70 at a shop later.

If you'd like to take a look at 'em, and/or discuss the bounce issue in person, I'll be around tonight if you don't mind making the trip up to Reno. I live in the South Meadows area so it's not terribly far from Carson. PM me for my phone number.
