cornerweighted my car

I cornerweighted my car yesterday. Unfortunately, I was not happy with the results.
Here are the numbers:

LF 801 RF 643
LR 583 RR 605
Total: 2633

Cross: 1227 46.6%
Left: 1384 52.5%
Rear: 1188 45.1%

Obviously, I need to reduce the weight on the left front corner, and therein lies a difficult decision. I really want to keep my A/C and power steering, but I might have found a solution. I might have an aluminum adapter made to mount the A/C compressor, move the battery to the AFM's location (or behind passenger seat), eliminate the AFM, go turbo (adding weight also to the passenger side), and convert to a manual steering rack. It's drastic, but would probably help the left/right balance, and bring the car into a better counterweight balance.

I also will be adding some weight in the rear with some additional modifications soon.

What kind of shop did you take your car too? I would like to do the same, however, I have no idea where to go.

I just relocated my battery to the rear compartment and I'm using the Hawker battery. The engine bay looks so much better and it definitely reduced the weight.

Any race shop should be able to do it. I borrowed a friend's scales to do it with. He has a race shop.

I did it at home with a grain scale we have in our garage.

Why not install height adjustable coil-overs and adjustable end links on the sway bars. These allow a competent race shop to balance the weight distribution along with proper alignment to really optimize the suspension. The adjustable end links allow you to set the pre-load of the sway bar to zero. Just make sure they do it with you sitting in the driver's seat or with equivalent weight in the seat.

I did this a few years back and the car came alive!

That would definately be a lot easier solution. Plus it has more benefits. I was gonna say that but twokrx7 got to it before me.

I agree with twokrx7. Cornerweighting is done with coilovers. Of course camber/caster plates and an adjustable rear camber link will help too. Because few have well proportioned placement of parts like the battery, power steering, AC or the such, you will end up with a car that is slightly lower on the passenger side. After cornerweighting, my car front rear difference was less than 30lbs. lefr to right and cross was at almost 50%. This set up does however remove quite a bit of the natural understeer these cars have. Get rid of the rear steering and your on your way getting this car through a corner the quick way. Now all you have to worry about is camber, caster, toe, spring rates, dampening rates, compression rates, sway bars, ride height, ahhhhh does this ever end?
