So you would go softer in the front than the original springs? Why?

Can you guys confirm if you are running camber plates. I defn want to get the ohlins but don't want to run plates as this is for street use.

Thanks.

I don't, I'm just using the fixed Dinan camber plates, i.e. not adjustable ones like the Vorshlag. Tried to put on the Ground Control plates but they don't fit.

Im not running camber plates at all, just front M3 suspension parts which give you some extrea negative camber

You can use the stock upper strut mounts. There is no need for camber plates on a street car.

Add the M3 front arms for a bit more camber if needed.

BTW, the OP lists the spring rates as backwards. This kit is 60 N/mm (~343#) in the front and 70 N/mm (~400#) in the rear, not the other way around.

Also, I spent about 15 or 20 minutes on the phone with Jeff from Öhlins USA, and he really cautioned against a knee-jerk upgrade of spring rates. He insisted that the kit had been thoroughly R&D'ed and the chosen spring rates had everything to do with the valving of the dampers as well as their unique DFV technology. He also suggested not to increase spring rates by >30% over stock without revalving. YMMV, just putting out what I heard.

Personally, I'm going to try the stock springs first, play with settings a bit, and see how it feels in daily driving as well as on the track.

I've been running the Ohlins with Swift 336F / 672R for a few weeks and am pleased with the combination.. Mostly daily driving and one solid run on mountain roads to date. Comfort level is great and the composure / balance is significantly improved. Currently running damping at half for front and rear but will continue to experiment.

why so high at the back? wouldn't a rollbar upgrade be a more efficient way of tying the rear end down?

We have sold at least 10 of these R&T kits, but over half of the guys just aren't on the forums at all.

You may want to do a search on E90post.com and 1addicts.com for additional reviews.
