1) replaced the RFTs with non-RFTs - handling went for a crapper (front tires rolled over on hard cornering), ride was beautiful - using Dinan Stage 2 tune (still in warranty) - not happy
2) Change suspension - Dinan Stage 3 (springs shocks, front sway, camber plates), added front M3 tension and wishbones - handling very firm, much improved handling and performance - change tune to Procede, catless DPs, AR FMIC, DCI - somewhat happy.
3) change rear suspension - add subframe, M3 arms (upper and lower), rear sway, LSD - MUCH better handling, ride still f'n firm, add: Meth and Forged DVs - almost happy (happy with power)
4) add rear toe arms - car tracks straight where I point it - 90% at least, change to Procede 11-1 maps (power great) -HAPPY with whole package.

The point being the entire car was designed for very firm side wall tires and you can't just change those - you have to redesign things to match them like the M3 has.

I'm now at point 3) with my car (- meth), overall quite happy, and Procede Rev 2.5 upgrade and the Toe Arms are in the mail

Unfortunately it won't be until January that I'll have the toe links installed. But user impressions so far seem promising!
