JRZ 3 Way
I have JRZ 3-ways setup on my track s2000. It weighs about 2600 at this point and I'm running 17x9 wedssport tc105n's. I'm running CF Downforce fenders which are pretty wide.
My problem is on really high load turns on my faster laps (few times a day) my front fender will rub against my tires. I can hear it inside the car and I can see the wear marks on the fender. There's no tearing and the rub is mild.
Any advice on resolving this? I can't pull the fender out cause it's CF. I am max ride height on the adjustment. Do I need new springs and perches? Everything else about the setup is dialed in, I just need to fix the rubbing before my fenders rub off. I was debating trimming the fenders but I worry that I'll do that and I will still rub on a now weaker fender. Any advice? Thanks!

In my case I literally bent the tabs up. I still rub a tiny bit under full compression, but it works! I assume though your fender tabs are also CF and you can't bend them?

Hi All! Thanks for the replies. I love my dedicated S2k, but I clearly know nothing about car setup...
I need to measure my ride height. I bought the suspension used and kept the springs/perches/etc from the seller. I'm fine with the rubbing except that it's starting to damage the fenders up front (the very outside lip). I'll try to post a picture tomorrow. My mechanic says that my suspension travel and ride height are maxed for the current setup and increasing ride height will require a suspension rebuild. I don't think that's right?
Ideally I can swap the springs/perches and gain maybe a 1/4" or 1/3", just enough to not damage the fender lip. If this is feasible can you point me to a vendor who carries the perches/springs I need? I tried Sakebomb/Motounlimited but they don't deal with JRZs.

I would probably call Karcepts for parts and service with regards to your JRZs
I think I have seen those JRZs for sale before, if I remember it was like a customized Auto cross setup
Are you running helper/tender springs?
If the shock(s) were blown, you'd have to be running a fairly low spring rate and/or no helper/springs for the shock travel to be that diminished. High end race shocks like your JRZs I would have to imagine are running at least 700+ lbs/in spring rates, which would barely sag unless your cross weights and front to rear weight weight balance were all messed up.
Btw, if it's just the outside lip on your fender and you are running 17x9 tc105ns, are you running the +49 offset? Any weird spacers? What tire size are you running? What about your alignment?
