Although the D?A are better dampers than the S/A koni yellow, they are still fixed length. Fixed length dampers = no ability to modify your ride height independent from your springs preload/sag. In the rear, strut length directly impacts bump/droop distribution without affecting ride height. Someone just posted about how their Tckline D/A cause their rear control arms to contact the chassis. That shouldn't happen and if you could just make the strut length longer it wouldn't. Lowside acknowledged the Tcklines weren't that great on the E82. It's in his build thread. Ohlin's issues pretty much mirror the TcKline since they are also fixed length dampers. Felix also has a 10 page thread on the changes he had to make to his Ohlin's. Some good reading in there if you haven't already been through it. Neither setup allows for caster adjustment either which can play a big roll in how camber changes in roll. Ohlins come valved for 6k/7k spring rates which means putting 500/700 lb springs on them probably results in pretty poor damping. Further, Ohlins for the F22 chassis come with 6k/16k spring rates and that chassis uses the same HA-5 multi-link rear-end. Why the change? It's my opinion that both these "coilovers" are a perfect example of paying a premium for a brand name that in reality offers very little. That might be just fine for you if you're willing to work around the limitations of them. Quote:

I run 70N/mm front and 160N/mm rear on my Öhlins (with 1M valving) with no front sway bar and a 12mm rear sway bar. The car feels absolutely fantastic.
It’s super stable at high speeds and is highly entertaining and eager in slow technical sections (did I mention it’s entertaining?).

I ended up with meister zetacrd coilovers, 12k/mm springs and I'm very happy with them.
First track event was delayed due to covid. I had the rear too stiff at first and struggled with oversteer using square 245 hankook rs4. Switched to 5 clicks away from full soft and that helped a ton, I will probably go full soft in rear, possibly lighter rear swaybar it is hard to put the power down! any power oversteer really scrubbed speed I have a larger oil cooler but not large enough it'll be getting a second soon, hit oil temp reduced power in the last two sessions yesterday. might have too much rear swaybar, the steering has to be unwound quite a bit or I get wheelspin in 3rd and lots of power oversteer tire wear looked great, much better than my r53 mini, running -2.8 front and -1.5 rear with slight toe out front and slight toe in rear. I did not bring pyrometer but wear looked pretty even not sure I should add any more rear camber it's trying to put the power down on a small contact page on the inside of inside rear tire. I would like to get a LSD but I think i need more aero/cooling first. Not as much lateral grip as my mini, no mistaking the weight difference, probably could use bigger tires on both ends, I may buy some used front fenders for hpde use and let the fronts hang out a bit, nothing a saw cant fix lol FSP cars.... another option is shorter front swift springs and moving the perch up above the tire, I believe I have enough room.
