i would like to get front 17x7.5 and 17x8.5 in the rear and the offset is 30 also i have kw coilovers, if you know the springs sit really low i would need a spacer, what size i dont know...... aslo i have the willwood braks.... any help would be great.... pm me if its okay thanks alote again

 

That offset would definitely push the wheels & tires past the arches & cause rubbing.

A spacer would just make the problem worse.

 

i understand that it will cause rubbing, but what if i roll the arches just a little to counter that problem? i mean how much could it really stick out?
my main problem is the fronts.... because i do have kw's the springs sit really low and i dont want to have any problems with that

 

Just curious, what's the point of staggering wider wheels in the back on a front wheel drive car?

 

For the aesthetic purposes of achieving a proper looking stance. Also, there's more room in the back. You can easily fit nines on the rear to get that wide wheel, deep lip look...but fitting 9's up front can be incredibly difficult so people often run thinner wheels up front...7.5's or 8's.

You'll be able to fit them with some work. You'll need to stretch the tires on the rear...but wider, lower offset wheels have been fit on MINI's before. Your front's shouldn't be a worry...just throw some 205/40's on them.

 

I understand that..but I thought the purpose of wider rims in the back was for more traction on rear wheel drive cars? So this has nothing to do with making the MINI perform better, just look better?

 

Yes, entirely for looks. Definitely not for the race cars out there.

For performance oriented cars, you'd stagger the fronts wider.

 

Aww ok got it. Thanks!

 

Some people are interested in good lap times at the track days but aren't worried about their stance looking good. Others are interested in having a stance that looks good but aren't worried that their lap times would be a few seconds slower. Different strokes for different folks

To the OP-

These are 16x8 et33 205/40. About as flush to the arches as you can get. You can use an offset calculator to compare your setup to this one. You'll poke a little more (9mm) so some arch trimming and tire stretch will be required to avoid rubbing at lowered ride heights...but they will fit with proper tire sizing.

 

great thanks for the input, my main issue is that i have kw' coilovers and the springs sit really low at the front and when i put my car down low i mite hit the wheel, all im saying is if the offset on the rim 30, is okay or would i need some spacers

 

That's really gonna depend on exactly where the spring perch is for your current height. My buddy had 17x8 et35 wheels that didn't clear so he put on 5mm spacers which helped them clear just fine. This would suggest that your 7.5 et30 would clear ....but it's impossible to say for sure because the spring location varies between each ride height.

 

Dude the MINI is a FRONT WHEEL Drive!
And a tendency to understeerat 7/10ths?

 

I really don't understand either, its Swahili to me too Octane. Rally please talk him out of it, tell'em to go with your buddys fitment of 16x7.5 with 5mm spacers all around, a GAZILLION time better traction, especially with 225/50-16s. But it took me 4 years to buy something I knew was useless, but I always thought it looked good, but looks could not justify the $400 price tag. So, I got more back in taxes than usual, and found a JCW Alcantara Steering Wheel for $351 at Morristown, and bought it. Although completly senseless, I don't regret it, but I am not sure if I would spend on a mod, that common sense dictates a loss of performance and even saftey issues during spited driving.

 

I'm probably the wrong person to ask to talk people out of it. I was the first person to run rear stagger on a MINI and I absolutely love it. My r50 had stagger and my current R55 has stagger...I don't plan on ever changing that.

My car (as well as many MINIs) will never see a track. Running one inch wider in the rear will make VERY VERY little difference in day to day driving. Certainly not something that would ever cause safety issues. There were 3 or 4 staggered setups at the dragon which is about as intense as a public road gets and we had no issues with handling.

225/50/16's might provide a little more traction, but if you're just using your car to drive to work...who cares? A little extra traction making a right turn at a red light isn't something to worry about. My car is a normal daily driver, not a race car, I don't need the extra traction so I opted for a more aesthetically pleasing tire size that doesn't cause rubbing problems. The same is probably true for the original poster.

Like I said....different strokes for different folks. I understand and appreciate both schools of modifying.

 

I had to really carve up my rear wheel arches/liners/rear bumper to make sure my 16 x 7s W42mm off-set & 225/50R16s didn't rub...

It seems like the proposed set-up would be great to look at- Painful to drive : (

 

There's a big difference between the proposed tire sizing and the sizing you ran. It should be entirely possible to avoid any serious rubbing with his proposed setup. 225 is a really big tire, so it's understandable that you'd have to do some trimming.

I ran 15x8.5 et8 with 205's on my r50, and it was a great pleasure to drive. Very little rubbing. Tire sizing is very important when dealing with aggressive stances.
