How do you like the cams? I was just told it would be a good idea to upgrade the springs so. I'm already there so I will just change the springs when the cams are out.
I am going to be installing a set of Comp Cams Stage 3 N/A cams soon. I use the car for road racing only. Mods to the engine as it sits SW headers with H-pipe built mufflers dumped before the diff, 47lb injectors, CJ intake, Ford racing CAI milled out to 4.150", dual 67mm VMP throttle body, UPR...
Good info I am glad you were able to fix the issue. I also had a very bad fuel starvation issue even at 3/4 tank I fixed mine with the Sai Li GT350 fuel system I can run the car down to 1/8 tank on track without it having the fuel starvation issue. That's on e85 also.
Hello my name is Eric I am new to the group I hope to learn some new things and help out other members if I can. I have a 2015 mustang that is used for road racing here is a picture of it in action.
The car seems very stable in the rear. But the front feels like it dives into braking zones and the front seems to roll in corners. My biggest issue is my front shocks bottom out quite often on track even when I don't hit curbing.
Front sway bar rates are
P1:*65 N/mm (372 lbs/in)
P2:*83 N/mm (475 lbs/in)
P3:*90 N/mm (515 lbs/in)
Rear bar rates are
P1:*35 N/mm (198 lbs/in)
P2:*41 N/mm (234 lbs/in)
P3:*50 N/mm (285 lbs/in)
Aero mods on the car are Kognition designs wing 68" long 10" cord, Front splitter...
I just talked to a few company's that race the s550 they said I should jump up to a 600 to 700 pound front spring they said stay no more then 150lb split front to back.
I am just wanting to know what everyone is running for spring rates on true coilovers? My current setup is Ridetech level 2 coilovers and I am running 400lb front and 750lb rear I feel like the car is still under sprung. What is everyone's Spring rates?

I have the BMR solid diff bushings, delrin IRS sub frame bushings, Sway bars front and rear, Sway bar end links, Toe links, Vertical links, and Chassis jack rails. I would have to say I love the quality of BMR Parts.
