What am I giving up by not obtaining the tubular control arms, adjustable strut rods, and adjustable steering rods from Hotchkis? And on another note, will my factory replacement leafs with caltracs suck on the road course? I plan on finding out...
1) Seriously consider adjustable strut rods. Spend the extra $200 and buy from RMS. They will round out your front end with your already great suspension choices.
2) Firm Feel Stage III Steering Box. You want to have more fun than z06 guy right?
3) Don't waste $ on adjustable steering rods. Get 11/16" C-Body tie rods and PST solid sleeves
4) The center of gravity must change. Drop the car 3"
My apologies for not having the time to address a whole lot of your above questions. Good luck.
