I had a bunch of these made up last year for my E39 M5 Race car and I'm still running the original made set with zero problems. I need to sell a couple now as I'm in need of funds for a replacement transmission. These bushings feel great on the track and on the street. OEM bushings have a high failure rate and if your Beast sees any sort of hard braking, these are a must. I have tested these on my lightened race car on the track for multiple races and hundreds of laps and not once have I ever had an issue with vibration or shaking. Aaron from Brecus has also been running these on his E39 M5 street car and they feel excellent on the road and on the track with the same results I experienced.
I had these designed to be better then the Dinan Monoball systems which I don't believe would last on the track and these will give your front tire a much more even wear and better feel.
I am keeping two pairs for spares for the race car which leaves me with 3 sets of bushings ready to be shipped out and pressed into your car. If wanted, for the price of new control arms, I can get them pressed in for you and ship them directly to you so it's just a bolt-on part.
I'm not trying to make any money on these I just want what I have into them which is $500/pair and I will ship them for free. If you want them pressed into a control arm please PM me so I can see what my shops cost is on them.
Sorry about the small pictures...
