HAM8URGER Posted June 17, 2014 Report Share Posted June 17, 2014 i just bought a 280z, coils, 15x9 -0's, 205/50/15's and was wondering if i would need camber plates to clear the fenders. I can roll the fenders if needed. I see a lot of guys running 15x9 -0 with 205/50's but have no idea if fenders are rolled or if they are on stock camber. Keep in mind im looking for SLAMMED :) will i need camber plates or will i be good on stock camber? Help is appreciated oh and here are a couple crappy pics of my newly acquired z Quote Link to comment
datzenmike Posted June 17, 2014 Report Share Posted June 17, 2014 Using camber to fit tires is just wrong. It positions the weight of the car on the inside edge of the tire and wears them out in addition to affecting the handling... and almost as bad... looks like you couldn't figure out how to do it right. By right I mean getting a set of rims with the proper off set so they are inside the fender and the body can be lowered over them. Rear camber is worse as the tires will actually toe in as the car is lowered, (it's built into the rear suspension geometry) and toe in even more as the suspension compresses going over bumps or under acceleration. You can imagine how a sudden toe in tire on the rear of a car will affect the front steering. Naturally it toes out, or has less toe in when braking or driving through a sudden dip in the pavement. Many have success with fender rolling but that small inward curving of the fender lip is there for a reason. It add structural rigidity and strength. Flattening it will make the fender edge 'floppy' and easily deformed. Avoid if possible. When your car is lowered there is a tendency for the front and rear to add negative camber and the top will tilt inward toward the center of the car. All front strut and rear IRS cars will do this in varying degrees. If your top tire edge is inside the fender, lowering it should clear and fender rolling would assure this doesn't rub. If the tire is already outside the fender lip or close it will rub. Just take a look and imagine the car lowering down. Best thing here is to get rims that move the tire inward to start with. If your fronts tilt in excessively when lowered, camber plates can be used to add positive camber and move the tops outward to near stock position. (assuming this doesn't position them to rub, again proper rim off set would solve this) Rears can be corrected by slotting the cross member where the control arms mount. This corrects the rear camber by positioning the arm mounts higher from their new lowered position and the wheel is more vertical. Quote Link to comment

This is a cheap stance car only so I don't care. All I want to know is if i need camber plates or if I can get away with a roll and stock camber Quote Link to comment
datzenmike Posted June 17, 2014 Report Share Posted June 17, 2014 You tell me. Take a look. Are the top tire edges in or outside the top of the fender? The backs will always tip inwards as the body lowers. If close probably good. Fronts will but not as much so close may not. Rolling may work. It's not an easily answered question. It's a look see. Maybe. Stock tires and rims would be easier to gauge. Quote Link to comment

datzenmike Posted June 17, 2014 Report Share Posted June 17, 2014 Ahhh then it's a coin toss. Quote Link to comment
HAM8URGER Posted June 17, 2014 Author Report Share Posted June 17, 2014 Any stance guys with a z on here that can chime in? Quote Link to comment
