Now.......
I feel I'm at the limit with pushing my car, what do the pros out there recommend I switch my spring rates to? 750 front and 1050 rear? I'm not on a full rear coil over. The car is rarely driven on the street but she is street legal.

I've been down this road a couple years ago. I wrote about it back in mid-2017 across several posts in my build thread. Perhaps something in there is useful to you. Starts with the 2nd-to-last post on page 19:

Originally, I was at 600/800. I went to 750/1000----hated it. Couldn't turn in when entering high speed rounders. Went to 600/1000. Was pretty good. Went to 600/900, really liked it and that's where I am now. (My car weighs 3250 no fuel no driver. I weigh 170lbs)
Bryan Hise from JRZ is very adamant that, on a quality damper, stiff springs are a myth. He claimed a JRZ suspension should feel "plush" (his word). When you go too stiff, you reduce the damper's ability to move freely and make subtle changes with the surface. That was definitely what I experienced. On 750/1000, I felt like the tires were just scraping across the ground when trying to turn in. I lost several mph on high speed rounder turn in.
You say you're at the limit......then I would say, there are better tires out there than an R1. Personally, I think you have the right springs for that suspension and weight of the car. Move up to slicks.
Anyway, don't just take my word for it. I'll repeat what Bryan said to me-----springs are cheap....there's no harm in trying. |
Thank you! I'll look over your past thread.
I do like these R1's granted they aren't a full spec race slick. Best I felt were the Pirelli DH's.
Most importantly I'll give MCS a call or ANZE. After today's event I feel it's time to send my dampers for some rebuilding. Realistically they should be rebuilt every year if you do 10-15 events a year and I have yet to do so (2 years ownership, 2nd hand MCS's)
