    welcome to the fun...

    GSR parts are everywhere. this is a good and bad thing for you, as there are good and bad parts available. don't be affraid to ask if you don't know the quality of a part - remember that what roadracing needs is different from drag racing in terms of suspension, brakes, and pretty much everything else, so don't expect that good experiences with a product in a strait line will necessarily corelate to good success on the road race track, though in many cases they do. you have seen a lot of good feedback already.

    I'll add comments about brake pads: Hawk makes a newer line called DTC. you'll likely enjoy the DTC-60s. porterfields are known to be good as well, and there are good compounds from carbotech and cobalt, and others. Hawk Blues are the old standard, and while they work well, newer compounds are better in a lot of ways including feel, modulation, wear, and rotor friendliness.

    harmonic dampers - you will have better throttle response without, but theoretically better engine life with. we've eaten an oil pump over the bumpy paving at sebring but I don't know that a damper would have helped that. supposedly you will see more peak HP on a dyno with a damper but the acceleration decrease will tend to hurt you more on a road course.

    engine wiring is a strange topic these days. certain sensors can be added or replaced (MAP, TPS) while others must be equivalent to stock. crank position can only be used where it was available as stock, and distributor internals are open, but you must use the distributor to dole out the spark to the cylinders as was done from the factory. you may use a OBD1-2 adapter to your ECU or even rewire from a MoTec to the engine so long as you keep the stock harness in the car and use only the stock or allowed alternate sensors. you'll find that distributor signals fluctuate due to the belt drive, and it's often easier to go to a lower resolution signal than a higher one to avoid the noise. make sure you read the GCR, particularly the ITCS before cutting anything.

    Remember the golden rule in IT is "IIDSYCYC" (If It Doesn't Say You Can, You Can't). there's a lot of performance paradigms that IT breaks. be aware - and when in doubt, ask.

    post some pics and keep us updated!
