Issues with handling at the track, seasoned track guys please help!
Very common issue with the SPC products...I don't recommend SPC products for Track usage...
Sooooo I think I found out the issue.
The rear driver's SPC camber arm is defective and has play on it. I have reached out to SPC and conference the head tech in, and they are going to call me back. SPC mentioned only sending me the part that is defective, but I requested to have the whole arm replaced (both sides), as I'm now pretty skeptic of the item, and would like to do a full replacement so nothing bad happens at the track. Don't know if they will.
Autoglitz also recommended me to get a solid axle bushing pressed in, and that I should replace my front tires as I have camber wear on them.
I am considering stepping up to 275/35/19s on my 9.5 fronts, to go with my 305/30/19 on my 10.5 rears. Thoughts?
Will keep you guys posted on the SPC thing once I hear back from them. Thanks again for the inputs

Hey, whats to give the guys who helped me out an update:
After a month of back and forth btw shops, just finalized the car's suspension overhaul.
I'm very happy to say that car is driving AMAZING. I actually don't think it has ever driven as well as it is now. I'm so pumped on how it just grabs the road in turns, and it feels incredibly safe at high speeds as well!
I spent a long time speaking to Orlando, the owner of Autoglitz which is the premier Aligment shop in SoFla, discussing my goals, it's tough to conciliate the perfect balance between a car that is a DD (50miles a day) but still a pretty much a track car, and IMHO he was able to tune it perfectly. Carlos, his right hand man also helped me out so much. That shop is top notch, and I highly recommend them.
The new parts include the 275/30/19 fronts, solid transmission bushing, front spc camber kit, revised spc rear camber arms with toe bolts, ears, nismo diff cover, and new poly bushings to all bushings that had not been changed yet. BC Coils, Stillen Sways and the 305/30 rears were already in car.
Will be taking the car to Homestead Raceway for a full track day on the 20th and will see if the sway bar settings have to be changed at all, but I don't think so from just the very high spirited driving that I did to test the new setup.
I'm happy with the new brake setup as well. Carbotech XP8s in rear, and Carbotech Bobcats in front. Bobcats is their street pad. I will swap fronts to XP10s during track days.
Pic of the rear... the solid bushing has a few love taps in order to get it in there since the old one was is pretty bad shape...

I know i agree with you, but since im doing so much driving during the weekdays (hour commute at 85 mph) i was eating too much tire (i was running 3 before), so i compromised and decided to lose some performance at the track. Im still running as agressive as possible within oem specs
