If you already have the M3 rear sway then the F/R balance is, uh, radical. Definitely get the PSS10s on to even things out and control wheel movement better. But with that much rear sway you still have got to get a LSD or you will be a cripple.
Oh, and stick to the Alpina for racing; the E93 is not meant for the track.

1/ Tires
my e93 is currently on yokohamo advan sport, was told that dunlop street / racing DZ1 would give me ALOT more grip. thought i would bite the bullet and switch out to the dunlops, and try to sell the yokos - even though my yokos are practically new.
will the dunlops be that much better to make the switch worth it ?
2/ re: M rear sway
unfortunately, due to occasional bad road conditions here and dealer recommendation: my car came with STOCK (non sport) suspension...my first week of driving, i did not like the floaty feel so i had installed a M3 rear sway....car immediately seemed much better on highways.
since stock front sway and M sway are the same, why would installing the rear M sway kill make me way unbalanced??
.
..this is basically the M3 sway setup correct?
3/ re racing
i agree the alpina is much better for circuit racing.
i want to setup the 335 for best handling (without sacrificing too much car comfort) because i want to canyon run with my friends who have porsches and heavily modified european M3s.
lastly, due to very high altitude here, my modded 335 is relatively VERY fast. thought the dunlops would help with my occasional 1/4 mile challenge races.
under the above circumstances, what do you think doc ?
First the shocks, the braces you mentioned, or the dunlops?
what would you do second??
thanks alot, cause i am lost suspension-wise.
