So I finally got around to corner weighting my car. For those who don't know the car its a 91 Lingenfelter 368, headers, 3in exhaust with DRM coilovers. I've done a few weight saving tricks including no spare, lighter battery relocated to rear crossmember, manual seat tracks, etc. Also has a large Ron Davis radiator which I'm sure adds a few pounds.
Gas tank was about 80% full.

Baseline - with 240lb driver
LF 907 RF 926
LR 954 RR 835

Final - with 240lb driver
LF 934 RF 916
LR 927 RR 844

Somewhere in the middle of the process we also noted:

No driver
LF 874 RF 900 Front total 1774
LR 813 RR 799 Rear total 1612
Total weight 3386

154lb driver
LF 923 RF 906
LR 878 RR 833

Anyhow just thought I'd share, looks like I still need to get a lot of weight off the nose.
Another thing we ran into is that the rear coilovers were binding a little, we had to add a couple of washers to move them inward. Also curious as to why the DRM kit has no lock rings, I noticed another car in the shop (Cobra kit) with coilovers and it had locking rings below the adjusting nuts.

Looks like about 51% wedge. That's pretty good.

Do you know what you'd like it to be?

50% is ideal for the street. A little > 50% is good for a road racing track with mostly right turns. I don't know about drag racing.

Once you know what you want it to be (if not 51%), you'll want to know your current and desired ride height (at each corner), then you can determine which spring perches to raise or lower. Make sense?
