M3 suspension conversion on 135i ?

[GaryS]

The surest bet is a BMW performance suspension. Everyone likes it.

I think it is cheaper to get the M1 for ~10.000 € more than the 135i. It is a whole package with M3 suspension, new engine, and M bits (seats, steering wheel, body kit, exhaust,...).

It is??? Cool! Can you point me to where I can get one of those?

M3 front control arm kit
M3 rear guide rod kit

Eibach PRO-KIT Plus Performance Springs (Set of 4 Springs) w/ F&R
Sway Bars
KONI Sport Yellow adjustable shocks/struts

Wavetrac LSD

Yokohama S-Drives
and yes an alignment

Have a 2008 135i Manual with the sports package

Your parts list look good for a street duty car.

Go with M3 ARB and not aftermarket ones.

I have been debating what M3 parts to add. I have KW V2 coilovers and the ride was GREATLY improved. Have been wondering if adding the M3 sway bar is worth it and what size (26.5 or 28) and if I should consider the front control arm kit. Purpose: spirited driving, occasional track use (1-2/yr)

So I'll keep you posted if anything changes. I also recently did a seat swap with a '12 M3 and they look so much better in my opinion except I can't get the adjustable bolsters or lumbar to buttons to work. I'm guessing it's a wiring harness issue, that my car wasn't wired for that option since my original seats did not have those features, just power.

6 years, 3 months and 25 days. Might be a new record.

On this board . . . . Seriously, I wish there was a necro-thread warning.

I find the arguments against the M3 arms interesting. It shows that there are varying levels of driver skill/involvement going on here and that some understand dynamcis while others try to justify purchases.
Just more proof that everything does not apply to everyone.
