The black flex plates that schreffler used were the thing ones that i now do in standard color fiberglass. Running the set screws will increase steering and going to the .018 front springs will increase front roll and rotation. You can also try a copper center spring to help keep the car flatter in the rear. I am testing new front springs this weekend that should really help increase rotation and if they do what i figure they will, I will be going into production on them immediately.

Jason,
do you have a front ride height required spacer spreadsheet anywhere? I do I need to guess or measure what I current have for spacers and go from there? I feeling lazy where's the spreadsheet?

I use this formula to calculate ride height for the front using the IRS arms and the BMI spacers:

Ride Height = (Tire Diameter/2) - (12mm + Ride Height Adapter)

So far it has got me super close to the ride heights I want.

Im juggling new products right now. The springs will be tested on sunday and if all is good then i will go into production immediately. Pod droop adjuster will follow shortly after the release of our DB10R.

I have an equation for the rear ride height as well but since I am running a different car my rear pod measurement will probably be different. The measurement you need is the axle centerline with the 0 ride height adapter. For now let's call this measurment X in the equation. Note this is also using the IRS ride height adapters like the BMI uses:

Ride Height = (Tire Diameter/2)-(X-Ride Height Adapter)

Any standard sedan size springs. We are running 13-14.5lb springs on asphalt and 14.5-17lb. springs on carpet.
