SportMax/XXR 002 on a B15

[DerrtyByrd]

I love the Sportmax/XXR 002 rims. But i have a 02 Sentra SER SpecV. It doesnt have the Brembo Brake upgrade. So i wanna do the 16x8 with the +15 offset. Yeah i know the will stick out. But how far? I was told about 1.5". I wanna go for that Old School Nissan/Datsun look, with a lip. I keep seeing the Scion Xb and Xa with these rims and fender flares. I plan on doing fender flares. Not quite sure the tire i'm gonna go with. Probably the 205/50 or 205/45-16. Any suggestions? Or problems with the suspension i might run into?

You can do it, you will need flares, and stiff suspension to keep from rubbing on the fenders, but it is possible.

That being said, I would not suggest it. You need to realize, your car was never designed to run that style of rolling stock. You will be seriously messing with all sorts of things.

Here are just a few things to keep in mind if you decided to run these wheels.

Scrub radius, by pushing the center of the contact patch so far from the steering axis, you will greatly increase your scrub radius. This will cause a few different problems.

Torque steer, by increasing the scrub radius, you will greatly increase torque steer to the point of making the car difficult to control under heavy acceleration.

Braking torque, this is the opposite of torque steer, because the wheels are so far out, they will exert a large amount of force on the steering wheel, causing erratic braking. Even small ruts on the road can cause the steering wheel to jerk violently under moderate braking.

Tire wear, the sever change of geometry is likely to cause nasty tire wear issues.

Front end longevity, the changes in geometry will put an increased amount of stress on the front end. You will notice ball joints, wheel bearings, and tie rods failing at an accelerated rate due to the extra stress. The effective increase of SAI will also put extra stress on power steering components.

If you plan to daily drive this car, I would look into wheels that more closely match the factory specs, the day to day driveability will be much better, and the car will be much safer to drive. If this is just a show car, knock yourself out.

Thanks... Now i know this is a Nissan/Infiniti forum... But how are the Scion's acheiving this? They are FWD... so are they running upgraded suspension to strengthen the hardware? And do we have it available for the B15? Once again i know this is a Nissan forum but do anyone have the answer?

They are just dealing with the increased failure rate. Most of these kids these days (read Scion owners) wont own their car long enough for it to matter, they do it just for looks without understanding the consequences. I would bet most of them are not daily driven, and they have so few miles that for most of them, its not yet a problem. Also, the XA/XB are under powered, and they produce almost no torque, while your QR25 is rather torque, you will have a harder time putting that extra torque down.

You could get some heim joint tie rods, with beefy inners, as they would take the abuse better. As for ball joints, Im not sure whats available for the B15s, but Im sure a Moog part will deal with quite a beating. As for the wheels bearings, you will just have to put up with replacing them on a regular basis, which, depending on your driving habits, may be as often as every 10K miles or so.

I would also suggest getting some decent coilovers, without them, you will be cutting up your tires on the fenders any time you hit a bump. You could risk blowing tires, or even denting your fenders.

Another thing to keep in mind, you will need to remove your inner fender liner, as the extended turn will most likely cause rubbing on hard turns.

Thanks now that's what i've been trying to find out. Mad props.
