I am in the process of changing my suspension components.I have ordered advanced design coilovers 950/700 springs.I am also considering removeing the rear sway bar after seeing data produced by Jeff Brauch on the track and skid pad.
Has anybody run their supra with no rear bar, apparently this is done on front engine rear wheel drive cars to get the power to the ground better.

Not that it would apply to anything you or us in here would be interested in, but I'd bet some of the drag racers have removed the rear bar. I don't recall anyone ever mentioning it relative to road racing though. Interesting experiment ...I read your info on Jeff's results so maybe not so experimental. Please let us know how it works out.

Thanks, Terry. 1.4g is... crazy. Do you know what spring rates Jeff was running?
950 front
700 rear

I've never tried it, but it might work. Sway bars work by lifting on the inside wheel, so they decrease traction at that wheel (although the LSD may transfer enough power to offset that). I think I remember Kent Rafferty saying it didn't help for autoxing, but the dynamics of autox are different enough from track driving that the same may not apply, so it 's worth trying.

I just wish I had enough power that it was a big problem.....

I had someone driving behind me at the streets of willow last weekend and said that I was lifting a wheel on certain corners, my car is very stiff with the six point cage. I'll let you know how it works but it will be june before I have the new setup.

I ran without the rear bar for a couple events until I got larger diameter sways. This was on Tein Flex coilovers with thier stock rates. I don't recall my alignment settings. It worked ok, but my spring rates weren't high enough to compensate for the lack of the rear bar...

Are you going to be using the same rates? If so I'd imagine it would work. I believe Jeff was using stock front bar as well? I wish someone made adjustable rodends for us.

Yes I am going with the same rates, I agree adjustable rod ends would be great.
