Megan Racing Roll Center Adjuster (Corolla AE86 83-87)
The AE86 Toyota Corolla is already 20 years old, and yet to this day remains an reckoning force in motor-sports. Most predominantly used in drifting, the AE86 dominates the drift series against opponents with overwhelming power and advanced technology while sticking to the basics of performance with balance and agility.
The AE86 Corolla is well balanced and is most often powered by the race-proven 4A-GE motors that transfer energy through their FR-Drive-train. Though this vehicle is an amazing vehicle in it s stock form, it always leaves something to be desired for the truth enthusiast who has the need to bring the most out of their performance machine.
Megan Racing is now taking on the AE86 Corolla GT-S/SR5 by unveiling a series of performance parts. These roll center adjusters are designed to improve suspension geometry on a lowered AE86 Corolla. The roll center is dramatically lowered, sometimes below ground level when the chassis is lowered drastic amounts that the front lower control arms start pointing towards the sky. When this happens, the car has a greater tendency to induce body roll all from the fact that the roll center becomes too low. At this point, even the benefits of a lower center of gravity from lowering the vehicle becomes outweighed by negatively affecting the roll center.
These roll center adjusters act as a spacer to bring the front lower control arms lower, effectively negating part of the angle lost when lowering the vehicle. Without these roll center adjusters, a drastically lowered AE86 Corolla has to rely on its static spring rate to keep the car from rolling over, but unless you are running extreme spring rates, the car will still roll-over because of the suspension geometry.
As a result, weight transfer is decreased and vehicle stability is increased by keeping the roll center above ground-- the higher the roll center is, the better it is for suspension geometry.
