Ohlins updated it's R&T coil-over for our car

Ohlins didn't change the spring rate and says confidently that 4K 3K spring rate is a great setup. I wonder what's the differences between the new one and the old one. Maybe more shock travel?

I found this a few weeks ago when I was trying to order the spacers I lost for the top mounts and endlinks... the manual is a lot more detailed for the SUS MP21 vs the SUS MP20, and actually lists part numbers! Unfortunately, part numbers for all the spacers were “bad” and could not be ordered. Jake from Ohlins USA said he was trying to get a package available to just order all the little bits and pieces that come with the Road and Track kit.
Also the MP21 comes with rubber spring seats.

Evidently the MP21 is TUV approved as well, MP20 is nothttps://uploads.tapatalk-cdn.com/201...cdb009f7c8.jpg

Maybe MP21 is for passing the TUV rules lol

Wait, 4k/3k, for real?

Not the only coilover mfg that puts softer than stock rates on their stuff or the completely wrong balance. Or wait, most of them do one of those things.

I am running the MP20 currently and I have to say the spring rates are very well matched to the car.
Stiffer doesn’t really mean better.

There were some posts about a knocking noise. Maybe the rubber spring seats solve this issue.

idkwhatimdoing: well matched with stock or not much different from stock grip level tires. Doubtful those rates matching that well with much grippier tires many trackday enthusiasts running.

4kg/mm front with 3 kg/mm rear doesn't really add up considering 0.95 front and 0.75 rear motion ratios. Wheel rates are ~3.6 kg/mm front and ~1.7 kg/mm rear, more than twice as stiff up front. Seems out of whack for a 54/46 F/R car with very modest power/weight...

This seems to be a common thought on this forum. FWIW, when I was on stock suspension and BFG R1Ss, my lap times were faster than T2s with Maxxis RC1s.
I'm not saying R1Ss are a great match for an otherwise stock car, but I really don't think the "matching" of the tires with suspension is as big of an issue as what most people here seem to think.
In the end, sticky tires = speed.

Pat: one CAN go on sticky tires and soft springs. It's just for that being far from best possible suspension setup. Sticky tires+soft springs=car rides on bumpstops. It drives, and grippy tires do grip, but how well dampening on bottomed out coilovers to bumpstops is, and especially if there happens to be rough surface or you are going over kerb.. Also for some too much roll may reduce confidence in pushing more in turns. It's subjective handling feel though, as grip is still there.
Somehow most common contra-question for "which coilovers" i've seen - "what tires".

I have taken speed “humps” at 30mph on these shocks with stock wheels and I’ve never hit the bump stops once, although I’m running the Raceseng 2 inchers on the rear.
I think one must be more open-minded to soft spring rates.

stock wheels? assuming probably also limited-grip stock primacies? Due which they may loose grip prior coilovers bottom out. Now take wider and much grippier compound half slicks & slicks, and it's easy ride on bumpstops almost every track curve before they'll loose grip.
I haven't denied that these might be very well matched to stock tires or when normally daily driving on public roads, both comfort & handling wise. Not so much for tires with lot of grip & on track. As in - way less 'track' in 'road & track' vs stiffer original MI20 R&T.

threads like this make me wish I can repurchase my old Ohlins to keep around for fun.
