Put in a 3inch alum spicer driveshaft today with some tubular lca's.. Man what a frikin difference the alum shaft has made.. I can do 100 and its so smooth !!! I love it, Should be the first thing m6 guys do to the car if it has the dreded viberations problems of the steel shaft !! The lca's are nice too. Gonna put the t/a girdle with some new c-clips in tommorow.

Very wise investment !!!

 

when were u getting the vibrations???

 

I get vibrations when going 120, any ideas?

 

anything above 75mph, felt like the rear end was gonna blow up. Did it with both my rear ends (3.42) and (3.73 current), The difference is night and day now, took it up to 120 and it was a smooth as 40 !!!

 

Where did you buy the driveshaft? How much?

 

I bought it off ebay for $232 to my door. New its $395 but this is for a spicer alum shaft aka the rk sport driveshaft...

You can find a 1le or ls1 alum shaft on ebay for prolly 200 to your door..

Well well well worth it !!!
