on my 1O1 style wheels i had a spacer of 2 cm rear and front. Is the offset of the 172 wheels the same? Do i have room for spacers or is the fenders filled completly?

According to realoem, you have some room for spacers in the front and rear. ET:18 front and ET:32 rear. I believe you can use 15mm for the rear and 5mm for the front. These are the same offsets as the 128s. I've seen the 128s and have recommend to NeRwEEzy that he could install 15mm spacers without any issues.

EDIT: I was editing my post at the same time NeRwEEzy was writing his.

that would be the same offsets as my rear wheels. and vt has advised me to get spacers put on.. 15mm. and i am planning to get them hopefully soon. that would bring the offsets to about 17 right? and compared to vt's setup, it would only be 1mm difference. i learned the whole offsets thing from him by the way haha.

At the bottom of this post I have typed some info on the wheels that I found on the ETK. I am comparing the 101's and 172's that were specifically designed to the E60. I know the 101's are available for other BMW models with different sizes and offsets, so I am assuming the 101's that you had were the correct ones for the E60 in which case the info at the bottom is correct.

It looks like the width and offset of the rear wheels are the same, so if the spacer worked with the 101's it should also work with the 172's.

The fronts on the other hand are 1/2 inch (12.7mm) wider and have an 18mm offset instead of 20mm. If the offset of the 172's had been the same as the 101's then the extra 12.7mm in width would have divided evenly (the inner lip would have been 6.35mm closer to the shock tower, and the outer lip would have been 6.35mm closer to the fender lip. However, since the 172's have an offset of 18mm (2mm less than the 101's) that means the extra 12.7mm will be divided such that the inner lip of the wheel would be 4.35mm closer to the shock tower while the outer lip of the wheel would be 8.35mm further out (closer to the fender lip).

So you have to judge whether there was an extra 8.5 or 9mm between the wheel/tire and the fender lip with your 101's. If so, then the spacers will probably work. Otherwise you may have to get different spacers for the front.

I calculated those numbers manually before finding the following offset calculator. If you wilsh you can go to the following website and plug in the number yourself. It gives an inner clearance of 4mm less (I calculated 4.35) and outer clearance of 8mm less (I calculated 8.35). Here's the link to the Offset Calculator---->>>>>CLICK HERE<<<<<


STYLE 101 for the E60:
8Jx19 ET20
9 1/2Jx19 ET32



STYLE 172:
8 1/2Jx19 ET18
9 1/2Jx19 ET32

Hi Rody,
Off topic a bit, but remember how worried you were about getting 166s b/c the tires would not provide enough rim protection and you showed my wheel/tire as an example? Well, I switched to General Exclaim UHP tires and these tires provide much better rim protection than my previous Toyo T1Rs. I was told that Michelin Pilot Sport PS2 provide even better rim protection.

That's good to know. Do they just have a bigger/wider wheel protection ring or are the actual tires fatter too? My issue isn't just about the wheel protection but also about the "look". With 275's on 9 1/2" wide wheels, and even more so 245's on 8 1/2" wheels the tires look like they are too narrow for the wheels and sort of "go in" at the top of the sidewall instead of having a slight bulge on the sidewall.

So in addition to having a better wheel protection strip do your tires also look a bit wider on the top of the sidewalls compared with the T1R's?

These new GE UHP tires look great cosmetically. I'm in Santa Monica this weekend. If you want to meet up today and check out my tires that's fine with me. Let's continue this via PM so that we can put this thread back on topic.

yes, my 1O1 i ordered with the dealer special for my R60 thanks guys very helpfull. I ordered blindly 15 mm spacer and a set of 2O mm spacers. So if the rear is the same the 2O mm spacer would work on the rear and maybe the front spacer of 15 mm will work also that i have to find out. If not i can always order new spacer for the front.

Thanks again guys.

With the 20mm on the rear wheels, you'll be flushed with the fender. You might be protruding out on the front with 15mm though.

yes front is now 3mm wider. I dont recal exacly if the front had space left. I remember the back was tight but i think i had room in the front even with the 2O mm spacer so i am hopefull. But i had a new spring set up now. Before i had the 35 lower hr springs and now i ordered the 5O mm lower springs (i have M suspension) so i have to find out. I know how lower the spring set up is that the wheels move in a inner motion towards the innner wheel; i mean the wheels move toward the middle of the car when the springs are pressed downwards. So the more lower the car gets with springs the more room the fenders have. It will be close i think but it might work.
