I have seen Jamex ads in several magazines. They are a German spring/shock company like Eibach. Had the rear springs out 2-3 times before I had the ride height the way I wanted it.
Had euro engine & std. trans with a few mods (200+ hp).
MB didn't & doesn't make a limited slip for this rear end.
I used the limited slip from a 190E 16V diff & had parts re-machined so that it would fit! That took 2-3 months & a bunch of $$$$$. Have a very good friend that has a REAL racecar, 280E that he raced for 4-5 years that will go over 160 at Daytona. His engine makes more than 300 hp & it's for sale.
Also had W126 (560SEL) brakes on the front. Car would go & stop!
