Whats the effect of the roll centre kit?
The kit came with 8 and 10...but I keep thinking HPI offered an aluminum upright option in 6...but I can't find it so I may be wrong (of course, we're talking 8 years ago too...LOL).
Lets you drop the CG of the car without changing the car's roll center basically. Or you can alter one end of the car's roll center by using a plate at the opposite end only.
We usually ran the rear plate then put spacers under the upper deck in the front with the Pro 2. This made the rear end feel more planted and the car more predictable overall.
Keep in mind though that the proper way to drive the car was always "on power". Except in modified at the end of the main straight (where they might tap the brake then get back on the throttle slightly before starting to turn), you were never off power completely. You always kept your finger pulling the trigger through the turns even if just slightly to keep your corner speed up. If you let it go into neutral in a turn the back end would want to come around.
I ran 27t stock with it and I don't think I ever was at anything less than 50% throttle even on tight, unprepared parking lot tracks.
