Not sure if you are aware, but once you have Race Start engaged, you can use the shift paddles to adjust the launch rpm up/down in increments of 100 rpm. I have yet to try Race Start one of these days, but the instructor at the AMG Driving Academy recommended 3200 rpm at least for the coupe. The sedan has less rubber in the rear, so you may wanna try an even lower launch rpm. Also a better tire will launch faster with much less wheel spin. The PS4S is currently the leader in longitudinal grip among UHP tires. It's not the fastest tire around a track, but it beats all its competitors consistently putting down the shortest braking distance in the wet or dry, which also means it'll have the most grip during acceleration. I definitely have significant less wheel spin now that I'm running the PS4S. Didn't even have to go wider in the rear. Just went for my first 200+ mile canyon run of the year today and it's a new animal with these tires. Much more communicative than before and much better road contact. The stock PSS crashed over road bumps and regularly skipped and lost traction under acceleration on less than perfect roads. It was a completely different experience today with the PS4S. Used to have to put the suspension in Comfort mode on some sections with the PSS to keep it on the road, but with the PS4S I could drive the entire run with suspension in S+ and the tires just stayed glued to the road. I'm very happy with the transformation. It was a super enjoyable day today.

the tires, for now still are the original PSS. When it s time to change I will see what’s the best solution. I think this tires will still last sometime.

How do you adjust the launch RPM w/ the paddles ?? ...I had no idea you could do that

You can see it in the beginning of the video.
You start the LC, and before releasing the brakes using the paddle shifter you can adjust the rpm, lowering with the downshift or improving rpm with the upshift.
In my case I was spinning a lot with 3500 rpm, and lowered it to 3000rpm. It did 4,64s to 62 mph. I still have to try launching it around 3200/3300.
Learning how to use the Dragy lol these are my fastest so far. I didn't have the best road. was dust all over it, traction was an issue even with my brand new PS4 295s on rear and i let off gas a bit at quarter mile as road had a bump ahead so had to brake for that a little early. I'll try some more soon! Want to get the best i can possibly do before renntech stage 2 goes on end of this month!

This RWD cars, have a learning curve.
It’s not like the AWD that do the 1/4 mile almost always the same since day one.
