Eibach Pro Kit with stock struts or must combo?

Do it right the first time man. I've had Pro Kits and adjustable Konis in mine since I bought it and I think its perfect for the street and carving through the hills. IF for the track though I'd really want beefier SWAY BARS/Anti roll bars though, especially if you are using sticky tyres. Also re tyres at a minimum I'd be using equivalent Ultra high performance tyres/Extreme performance eg. Federal RS-Rs, AD08s, etc. NOT Bob jane specials as an MR2 isn't really a car that you want sliding around all over the track - then you'll be right on the tail of that Integra ;)

Eibachs work with stock struts, but given the age of many SW20s, its often the struts are the problem in the first place.
 
Another option is we can get a set of BC coilovers or Megan racing coilovers for about $1200-1300 brand new to save the hassle of trying to get matched parts.

Hey dylmrt how is the ride quality with BC coilovers? Even on the softest settings, is it streetable?

I run BC's and I have no problem with them on the street. there also fully adjustable for track work as well

Have a mate who might have BC's, maybe I'll ask him for a ride. While we're on topic, how does Tokico Illuminas compare with Konis in terms of ease of use? In fact, can you change shock settings while it's already installed? Apparently there's 5 settings with Tokicos and Koni's have "infinite" adjustability which might make it confusing...

If you're upgrading brake pads, do the rear ones as well. Just upgrading the front will stuff up the brake bias. As for suspension, I got some BC racing inverted coilovers not too long ago. I played with the damper settings a little bit and it's actually not too bad on the street. You'd want to avoid potholes but it's not too uncomfortable. Just depends on what you define as comfortable. I'm yet to try them on the track but I'm sure they'll be a damn sight better than my 15 year old stock suspension. With 200hp your car should be able to keep up with a dc2 for sure. For tyres, get something like a kumho ku36, federal rsr, ad08 etc. Don't bother with ku31. Any of those "ordinary" street tyres overheat and get real slippery after only a handful of laps. The ones I listed will grip better and cope much better with the heat. They are still very forgiving, it's semi slicks that tend to be snappier on the limit.

Oh and the reason I mention KU31's is because is hard to find 205/45/16 size for my fronts (GTSt) but my alignment shops says 205/50/16 front would be more correct aspect ratio as my rears are 225/45/16? Would 205/50/16 give better grip or that's tyre pressures?
