Rear Suspension Setup: Lower Arms

nautiluscont said:

I recently purchased the BMR's adj. lower arms as well as the weld in relocation brackets. I understand that by doing this ultimately your changing the instant center of the car. Currently I have my lower arms adj to the stock length and plan on adj them at the track while logging my 60' times. Does anyone have a good length these should be adjusted to? I believe what it is doing is changing the pinion angle to slightly negative (pointing down) so that in theory, under acceleration the pinion should rotate upward ultimately lining up the pinion to zero degrees, maximizing efficency and use of power.
A neg. 1.5 degree pinion angle has been suggested. I hope to be able to dial the car in even better and lower my current 60' times of 1.70' to 1.50's. Any articles or opinions on adj. an adjustable 3-link suspension would be appreciated. Thanks
