New rear subframe bushings meaning the M3 bushings, or did he mean Delrin?

M3 bushings

very nice upgrades indeed.

Very nice! I got my Wavetrac LSD and KW V3 w/ Swift Springs from Harold too. I'm waiting on the M3 bits....I'll treat it as standard maintenance at the 60-76K mile period, lol.

But anyway..

threadstarter,
How much did all that run you for parts?

+1 I wonder how much to expect.

Great set up! Looks like nothing was overlooked.

i full m3 conversion front and back and have ast 5200 on order.. im still undecided on spring rates and type of springs.. are swift springs really superior to hyperco and really that high of rates for the back?? isn't 800 kinda stiff?? i was looking at 450 550

Park828 · 02-12-2010, 10:51 PM

by the way this would be for 99% daily driven street use and maybe track day or two a year...

800R is not high at all if you look at the wheel rates. You will want at least 400F and 800R, great for both street and track.

do you have a picture of the thrust sheets? what do they look like? and how much is a set?

You can see the thrust sheets in front of the springs here:

$25 for each set. You will need two sets for all 4 corners.

After a couple months of driving, any additional feedbacks?

Does this M3 conversion enable front wheel of 18x9.5 et 35? I believe 9.5" would not clear strut on stock e92 suspension, but how about on m3 suspension? The camber will be more making it closer to the strut, but the wider track takes the wheel further away from the strut so that the 9.5" front wheel would clear the strut? The wide front wheels would cure the rest of the understeer even with only 235 tires.

You will need a 5mm spacer and run at least -3 of camber with 265 tires. The camber does not move the tire any closer to the strut as the camber is adjusted via camber plates.
