I'm going to drop this post from the old Yahoo group here for future reference. Credit goes to Brian Brown.
I've used the M Coupe 19mm rear sway bar with an otherwise stock 318ti sport suspension. It works very well at reducing the tendency to understeer, but without making the car tail-happy.
Here's the part numbers for stuff that's different:
(1) 33 55 2 693 754 19mm rear stabilizer bar
(2) 33 55 1 094 551 19mm mounting bushings
(2) 31 35 1 124 995 Support straps for above bushings
Part numbers for the rest of the linkage hardware (same as original, but not a bad idea to replace):
(4) 31 33 1 092 887 Self-locking M8 collar nuts
(2) 33 55 1 135 307 Stabilizer end links <<<good idea to get new
(2) 33 32 1 127 717 End link brackets *
(2) 07 11 9 912 501 M8x43 hex bolts
(2) 07 12 9 964 655 Self-locking M8 nuts *
* I haven't tried this, but some people have reported using the stronger end link bracket from the front stabilizer in place of the original brackets listed above:
(2) 31 35 1 127 263 End link brackets
(2) 31 11 1 114 348 A10, 5x22 Flat washer
(2) 07 12 9 964 672 Self-locking M10 nuts
People with stock M-Coupes have been breaking the attachment tabs on the trailing arms (just like the E30's with aftermarket bars), so I would highly recommend welding in reinforcements when using this bar. Dinan sells prefabricated pieces of sheet metal to do this, but anybody that can weld could probably come up with some suitable pieces on their own. |
