Where can one get all the poly bushings for the rear at one place.Most places just have certian ones.While another place will have the others.
Are the power flex sub frame bushings as good as the polys or the same
I want the rear suspension to be as strong as possible (no flexing)
But I do drive it some on the street.

I got mine from http://www.bmw2002.com/

Better get rid of those flexy springs and shocks then...and those flexy tires while you are at it. :stickoutt

I have the h&r rear springs and turner solid trailing arm bushing and AA diff mount.I drag race the car so I need everything to stay in place with the slicks on.I have broke 2 axles so far and I think part of the problem is the rear is twisting way out of place and putting weird angles on the axles

What kind of tires are you running? Slicks or drag radials? I've never known axles to be a problem on these cars, even with lots of power. Are you modulating the clutch to get a good launch or just dropping it?

I broke one axle on the start and one on the 1-2 shift also broke two diff
housing. Im running the M/T drag radials Yes I modulate the clutch
or ease into off the line but not on the shifts.I actually take it alot easier than I want ot off the line

I don't think these car were meant to do 11 second runs... but wow nice running.

Thanks,I saw your car up at bay sox stadium last year Very nice I think we are two extremist just in diffrent sports :lol .I did not see you at the fed X event. What do you think of the power flex sub frame bushings or are the pure poly stronger.

I think the thing to bear in mind here is that circuit racing "lots of power' < Drag racing "lots of power", plus all that power comes home on repeated hard launches.

Broken rear ends are common in drag racing, especially with IRS rear ends on late model BMWs and turbocharged engines.

It's a whole different ball game engineering wise.

Hey kenny, I decided not to go solid frame bushings as the ride will just be to
harsh so Im looking into the urethane.I think I will try and go this route on evrything I can The custom axles should take care of the rest

Ulysses, some Urethane or Delrin bushings will be a vast improvement over OEM.

PowerFlex are the only Urethane that I know off. If it was an E30, then Ireland Eng would have them. :dunno

I was in Atlanta for the ProSolo instead of at FedEx. I'll be there next time. :)
