Hopefully I can find a pair of 5" springs before the weekend if that's the case :

I give it six months before the car has a huge wing and a cage.

6 months might be conservative That being said, I want to push the car to my limits without Aero but a cage is likely coming in that time frame.

So yesterday was a pretty successful 1st shakedown of the car... the only last minute event I could find was Thunderhill West which isn't the best track to test all aspects of a car (hoping to visit Buttonwillow soon) but I'll never complain about seat time.
I spent the last ~10 days getting Suspension, Brakes, Seats, SPL arms, fluids, plugs/coils, harness, etc installed. I planned an uneventful Friday but a local shop forgot to tighten my SPL arms after an alignment and the rear SPL Upper Arms were held on by 3-4 threads when I pulled into my garage (my rear toe was 14mm OUT at this point). I was pissed but refused to miss out on seat time so I spent the night doing a string alignment and praying my 295s would fit without issue. The track was pretty cold with ambients around 42* in the morning and with the late night I arrived after session #1 so I decided to run in 2 groups for double the seat time. The first session was mostly me pooping my pants as data showed I was entering T1 over 10mph faster vs. my last car (now without aero). I spun late in that session after the rear came out under hard braking so we looked at the alignment again and decided to add some rear toe-in (the car was really twitchy everywhere). After my 3rd session we realized that I was running 42psi hot since we were busy with alignment and hadn't checked pressure since we arrived . We dropped pressure to ~34psi hot for the second half of the day and I'm stunned by how stable and powerful this car is, the potential is incredible. I really can't imagine stock power + 295s + aero At the end of the day I ran a 1:24 flat which is about 1.2 seconds (2-3%) slower than my PB from my 380whp E82 with full aero and 350lbs less weight. What's the max front camber people are running with GC plates? I'm at -3* and it doesn't seem like I can go further until I install SPL arms or grind away some of the aluminum brace or modify the GC plates to pull the top mounts inward.

You do have to switch the the bolts around on the plate though to the race position.

Does anyone else run MCS 1WNR? I ran rebound at Front @ 10-11 from soft and Rear @ 9-10 from soft w/ 700/1000lbs springs. The track was pretty slow with a lot of 2nd gear turns and big berms so I kept rebound lower but would love to hear others settings. Kinda already regret not going 2WR... with the weight of this car I feel like Suspension compliance/mechanical grip is going to be super important until the aero bug bites. Also, the turn-in and steering feel wasn't ideal... obviously this was partly due to the 295s on a 10in wheel but I've always run upgraded front bushings in my BMWs, what are the best bang for buck front bushings to replace? Guessing tension arms and tie-rods?

I'll probably stick with the 1W's for a few track events so I can get more comfortable with the chassis as it's a dramatic change from E82. Also, a few of the time trial groups I run with have limits on 2-way / remote suspension. BW mentioned that the 2WNR's have been redesigned in recent months and are significantly better now - has anyone here been running 2WNRs for a long period of time?

I think the MCS 1WNR are a superb coil over. The lengthened body of the 1WNR & 2WNR are awesome. I asked a very talented/experienced driver that went from 2WR to 1WNR why he went to NR, he said the simplicity- 1 knob, turn and head out on track, no pressures no separate settings.
Some very fast SoCal drivers with E9x & F8x are running MCS 1WNR running mid to low 1:5x at Buttonwillow CW13. Those running 2WNR & remotes all seem to be the same and I don’t really recall anyone feeling the suspension configuration was holding them back. Majority of them previously have run many well known set rate coilovers and moved to custom MCS, JRZ, Moton, etc. I’m slow but I take & appreciate their personal feedback which made the choice to go with MCS a no brainer. It was more than I had set out to spend but not too much more for what is offered. Last edited by silverbackf8x; 01-17-2022 at 11:24 PM.. |

I've always run 1 ways in the past, I actually ran Fortune Auto custom tuned shocks on my E82 which were just about as fast as the MCSs I ran on that car. Similar digressive design with a larger monotube shock tube... I'll probably stick with 1 ways until I hit 1:55 flat at BW without aero... Love that we have the North American Time Attack measuring stick a few hours away at BWRP.

I had one of the first 2wr MCS for an e46 m3 back when people thought MCS' were vaporware, circa 2009-2010. I now have their latest 2wr on my full track build e46 m3. They're just as amazing as I remember. My buddy was following me in his own e46 with only the 1way setup no reservoirs and he said that i was so flat across berms it was incredible to observe while following.

The MCS 2WNR had a significant change, the ones sold now and the ones sold before are not at all the same.
I'm going to run MCS 3WR from now to the end of time. Super happy with them. Getting two sets for the GTS1&2 sometime this year. |

Yeah 2WR would be my ideal setup but bumps me into higher classes in a few of the time trial groups I run with. That extra volume must be incredible on track though.
