Why am I destroying my tire?
Why am I destroying my tire?
Last spring I replaced my fb's stock suspension with tokico hp's and racing beat springs. With 15x7 +20mm konig rewinds I really didn't have any tire rubbing issues. Since then, I replaced the tires on the car last summer with toyo proxes (205/50/15) which are the same size but different brand as what was originally mounted on the rewinds. However now, I just got the car out of storage and cannot take a fast right corner or hit any bump with the wheels turned without the left front tire scraping against the fender. This is pulling the lip of the fender down toward the tire while also cutting into the tread. I'm unhappy with the rb springs and was planning to replace them with re-speed coilovers, but will that solve my problem? The car is sits noticeably lower on the driver side and the left front is the only tire that rubs. Why didn't I have rubbing issues last season? Did the springs really "settle" that much in storage? I would prefer not to roll my fenders, but if it solves the issue so be it. Maybe racing beat should revise their spring design after I've read so many complaints about them on the forum.

I like my racing beat springs but i have them paired with some KONI struts. But I'm running a low offset (-10) wheel so i have rubbing issues. But when i use the stock GSL SE wheels (+40? offset), i don't have any issues.
I'm gonna just roll my front fenders and call it a day.

Different model tires are often different in physical size even though they may be both listed at 205/50/15, they can often have different shapes. And if the RB springs where new when you put them on they will settle a bit over time.
1st gen also tend to sag on the left front corner and IIRC there is a shim you can purchase from Mazdatrix(?) that will raise the left front corner.

Have you checked your tire pressure? If the setup didn't rub, and now is rubbing after storage, I'd check the tire pressure and functionality of that front strut, along with all the bushing, etc. I've had similar problems in the past (rear wheel rubbing) and the tire preessure was down about 3 psi. Also make sure the springs are properly inserted in the perch's.
I'll check the pressure, though it looks fine. The springs were new when installed and I was planning to replace all the bushings when I got re-speed parts. The car sits almost an inch lower on the left side, why do they all have that tendency? I've heard about the shim, but it kind of defeats the purpose of having a nice slightly lowered car. My car sits about the same as stock height if not higher on the right, I think the shape of the new tire is the problem here, might as well roll the fenders and order coilovers.

they sit lower on the driver side because the driver, battery, steering box and brake booster/master/pedal assy is all on that side.
if the tire is hitting the fender, negative camber will help too

Could be the spring may be weak, but I've had RB springs for 3 years with no noticeable difference in height, so an inch is a bit much for just sag. Perhaps your damper is leaking or blown. When you swap to the RE-speed parts, check your dampers while you have everything apart.
