15x7 and E21 hubs

Thanks for the additional info on your setup. So you’re running 5mm rear spacers, so in the rear your wheels are effectively 13x6 et8…

 

2002 track width varied a bit over the years. While mainly due to wheel changes (4.5” to 5” to 5.5” Turbo), but some was also directly due to hub differences. For example, the Turbo hubs/flanges definitely add track front and rear.  So it’s definitely possible the e21 hubs add some additional width up front (that many don’t notice). I’ve swapped to the Turbo set-up front and rear myself, and don’t have direct experience with those E21 hubs brake conversions.

 

Some additional thoughts…

- Many do a slight lowering of their suspension - and lowering adds camber, thus increasing outer tire clearance. Less camber, less clearance- your set-up looks tall with little camber.

- As stated, tire profiles vary from brand to brand - so a rounder tire edge will fit better than a square edged one for clearance. Your 185s look very square shouldered.

- Some folks tolerate slight rubbing issues in the extreme suspension cases (if they don’t race or get into those cases except rarely). The more it’s about the looks the more likely…

I think it is strange that someone uses this wheel setup with spacers and not have problems with stock fenders

I haven’t seen many folks discussing running spacers with the 15x7 et25s and 195/50s.

As to the E21 hubs, they don't really make a difference.  

 

I've gone between 2002 and E21 on several cars, and never

noticed a difference in clearance.  Or more accurately, a  lack  of clearance.

 

And that's with E21 turbines, E30 15x7 et28 OZ's, and E30 bottlecaps.

 

ET0 13" Panasports with 205-60 RA1's just would not fit in back for love nor money.

Which sucked, because I had a lot of them.

I was looking through "the stance thread" and some, not many said they used spacers. I have always thought that this was to avoid rubbing on the inside of the wheel when turning fully.

 

I have measured now and I have on the front axle 83mm from the face of the disk to where the caliper is mounted. I have not been able to find another strut, and I dont want to change the disc and hub just for measuring. If someone have the possibility to measure the same  distance on a stock setup that would be great.

 

I have also measured the rear disc setup and my spacer is 4.5mm and the disc is 5mm thick. I measured a drum and that is 8.5mm so actually I am 1mm out at the rear. Negligable.

Width of discs/drums doesn’t matter. It’s mounting face of the wheel/hub.

 

Maybe measure the track directly, if you think you’re wide?

 

You need mounting face to body center (x2) or to the opposite mounting face. Ideally, the loaded distance. And wheel width. And wheel offset. Note: tires don’t count in calculating track. Compare to Blue Book for your car.

 

If you’re wider, and have clearance concerns, from there you can determine the exact ET for a 15x7 you’d prefer.

 

Your car looks to sit high with almost no camber to the wheels. Do you have new springs? Have you had an alignment recently?

I have restored this car and finished that in 2014. I have may driven 1500 km with it since then. Everything is new, and I had an alignment done before starting to drive it.

 

I have measured the distance between the face of the disc to the best of my abilities. 

 

Front 1398mm

Rear 1384mm

 

Those numbers should have been exactly the same according to the specifications for a 02. 

 

The track width is 1331mm originally. The numbers I have provided is not the correct track width however. There is a calculation that includes the rim width and the offset to land on the correct number. Maybe someone knows how to calculate this?

 

Nevertheless, the front axle is wider by 14mm. Is this due to the E21 hubs and discs?

To my understanding track width would be measured from center of the tire to other side. If I recall right original ET is 29mm, atleast some configuration of -02, so 1331+2x29 would result 1389mm from the wheel mounting faces. Pretty close between your measurements? What makes the difference of those few millimeters can be many things. I believe the track is measured at the contact patch of the tires therefore because of some camber angle it is different measured from center of wheel. Then again why your measurements are different front to back? Is your car lowered from stock height? That would be most obvious reason to widen the front track.

Yes my car is lowered a little bit in the front. 1 spring round has been chopped off. Approx 20 mm I guess. That could be the answer to the differences.
