3a. Camber plates in the front and hardened tophats in the rear?
3b. Can someone educate me on what to look for in camber plates and a beginers guide to using them?
I hope that narrows it down for you Kevin 
Jonny, what do you mean by, "...how did you test your struts if they are still in a box..." I never said anything about testing my struts. |
1) No, unless you plan to go after a Divisional or National Championship in Solo 2.
2) My opinion here, but I'd say no higher than the 275/225 Steve mentioned. I never confirmed it, but based on butt-dyno comparisons, I think my car was close to 5k front 4k rear. I never did find anything remotely reliable about what the exact spring rates were. I do know that anything stiffer will basically shake apart the car after enough time, even if the ride hasn't annoyed you by then. So if you go with GCs, 250-275 front and 200-225 rear would be good, or you could save money and just get som SPTs or Prodrive springs. But there is an advantage to the GCs, which is they allow more camber adjustment if you have plates. On to number 3...
3) I had the STi Group N tophats, which do a great job of taking the play out of shock bound, but I long planned to switch to camber plates for camber adjustment. It's worth it to have the extra cmaber and toe at autocross, but still have reasonably conservative camber the rest of the time. Rear camber plates are hard to come by, so for those you might want to just use Group Ns. Besides, with bolts you can get up to -2.5 degrees, which is probably more than you want anyway. I loved having tons of rear camber personally, but I'm goofy when it comes to alignments. Racecomp just came out with GORGEOUS front camber plates, but they're expensive. Cusco makes some, and a couple other vendors. I personally would only get a type that only has one axis of adjustability, like the Cuscos, instead of the sliding plate type (MRT).
