Read the R&T review of the M2 and wondering how one might get more lateral skills into the S3.

Hierarchically, what happens first, then second then...

(Assuming one would want to keep the Mag Suspension)

Set of Pilot Sport Cup 2's would be a good start.

sticky tires, sways, end-links, tunnel brace, control arms with poly bushings, struct tower brace, rear chassis brace, coilovers, dog bone mount, lots of negative camber, wider wheels?

Sways are very tempting right now, I also want to stabilize the rear-end, it gets squirlly when you push it.

(I'll admit, I had to Google tunnel brace).

agreed. too much flexing going on. I've been waiting for 034 Motorsport to release a rear sway, they said they are working on them, but no dates yet.

H&R not a good option?

I've got a tunnel brace from Unibrace on my car. It definitely adds to rear end stability. Big difference. Am tempted by the Unibrace unit which joins the rear shock towers via a brace just behind the rear seat. On the fence with that. Will definitely be getting a thicker rear sway bar soon as well. I don't intend to track my car so the expensive of wider wheels and stickier rubber is out. Having a solid, stable cornering car while out for a spirited drive is important to me however. Also, and I'm probably way off base here, but don't AWD vehicles sort of in our price range tend to have designed slight understeer? Making RWD sports cars like the M2 a tad grippier with the inherent tendency to oversteer? Now once you get into the super or hyper car range, AWD is the answer obviously. Look at the 918 or LaFerrari or MP-1. Between the electric motors and computer controlled everything, hard to go wrong.

I think H&R designed their rear sway to work optimally with their front sway, so if you only go with a rear sway, getting a rear sway designed to work optimally with the OEM front sway would be better IMO. Also, 034 adds the grease nipple, so when your sway's bushings start to make noise, its far easier to re-grease.

I'm still somewhat undecided about getting both font+rear sways or just a rear sway though. With just a rear sway there will be more fun oversteer, but with both front+rear sways, it will further reduce body roll and improve turn-in "feel" to some extent, but it will shift the balance of the car to be somewhat more prone to understeer.

my thoughts exactly. i want to reduce understeer and improve cornering. i think the rear H&R is too thick to work with the oem front sway. any other options ohter than H&R?

BMW M2 Tires specs - 245/35R-19 in front and 265/35R-19 at the rear

265s would be sweet, and that might be one of the major reasons this car is pushing a .99 on the skid pad, but not going to put the money there.

Seems like stiffing up the car and some coil-overs (work with the Mag Suspension?) are where to start.
