You'll always want more, but it's a good start. If, or should I say when, you start swapping out wheels, tires, springs, coilover, camber plates, etc., the M3 bits keep paying dividends. That being said, I think your brothers will be surprised how capable the 135 can be on the street in stock trim.

If what you "want" has nothing to do with what you "need" you will always be wanting more. Clearly you have already been "left behind". If that depresses you, change the dynamic. Do a track school and learn how to actually enjoy your car. I applaud you for thinking about the suspension before adding power though - says there is hope! Go find out what you need by experiencing what you have on the track.

Well, "full" M3 suspension would include the M3 rear camber links, and they require new rear shocks, so you'd be replacing the POS shocks too. Also, HPA Shop has aftermarket rear toe arms as an option with their M3 conversion kit, which is also a big improvement. So yes, full M3 conversion is all you need for an awesome street suspension.

I most certainly have been left behind,yea I feel the car has more motor then chassis from the factory, I just was thinking of going with this set up cause I'd like the car to drive like a "natural" M feeling car and not so choppy in the back when I get into the twisties

do you think this is more cost effective then going with aftermarket coilovers with m3 control arms ?

Ditching the RFT's will get rid of a lot of the bouncy-ness. Replaced the rear axle bushings with the M3/1M ones will also get rid of the rear end wiggle and slop from the rear end when really throwing the car into the twisties.

My next mod will be the M3 suspension with probably Koni Yellows and Eibach lower springs. I really want the entire M3 suspension on my car. But so far just installing the M3 suspension bushings and switching to Michelin PS3's has transformed the way the car drives.

I think for street the highest priorities are non-RFT tires, better shocks and M3 front swaybar and rear subframe bushings.

If you buy Koni Sport shocks, you can convert them to coilovers later to lower the car.
