After installing my MPP sport coilovers last weekend, I finally had a chance to take it in the twisties. First things first, I am using what I consider to be a good street setting of 10R/12C, and lowered only 1/2 in. This is not too harsh IMO and it still handles great. Will those with a dainty back side like the ride, NO. Will those who are use to a sportscar like a Corvette or M3/M4, yes, most definitely yes. It is not harsh, but stout. Better over dips than stock, but not as smooth over rough road surfaces. My Corvette was way worse for comparison and had custom tuned DRM Bilstein shocks and Z51 suspension.
Before the coilovers:
Very unsettling over bumps mid corner when pushing it. The pogo-ing caused loss of grip and no confidence. My tires would also squeal making me think my beloved Michelin PS4s were not all that on the Tesla (tire of choice on the Vette in my group and many other groups). Ride quality of stock P3D was ok, but not great. Mostly an average ride quality, but harsh over bumps.
After Coilovers:
Que my best valley girl voice, O-Ma-God!!!!, does this thing handle now. My test run is up Little Tujunga Canyon (affectionately know as Little T) to try out any suspension mods. Very tight and undulating with elevation changes. With the new suspension, I was able to push and push and never did I lose grip, bottom out, or run wide. Did it pogo, not at all. Was it rough, not at all. How was the body roll, almost nonexistent comparatively speaking. Do I feel the need for thicker sway bars on the street, a resounding no. The coilovers do the trick, probably due to the stiffer springs. Could I go to stiffer R/C settings, maybe, but so far, so good. Would probably stiffen things up on track, maybe by 2 to 8R/10C (remember, lower numbers are stiffer), but for the street, I am happy. Oh, no noises to speak of thank goodness. Just the sound of my fan running high in track mode.
Is this mod worth the money, if you drive the canyons or track your car, most definitely. Not a question in my mind. If you just drive to work or to the corner Starbucks, probably not. For those with a dainty back side (being politically correct here), the sport coilovers with the comfort springs would probably be the ticket. Can't wait to run with my Vette group.
