Team Dynamics Wheels and Offsets

**cantfind1** · 16-03-2010, 08:12 AM

Okay so this seems to be done to death but just need some opinions.

I am going to get some track wheels and tyres not concerned about swapping wheels front to back so sizes are as follows

Front 18x9j et30(extends by 20mm over OEM CSL Rims) or et35(extends by 15mm over OEM CSL rims) Not sure if the 20mm extension will foul the arch with 235 tyres?

Rear 18x9j et 15(extends by 6mm over OEM CSL Rims) running 265 tyres on the rear.

All team dynamics wheels pro race 1.2 not sure if I can get 1.3's in these sizes, not sure of the benefits of the 1.3's over the 1.2's, any ideas?

Any thoughts on this set up welcome!?

Have been using this website to calculate the offsets

Standard et44 front foul the Arches just with 15mm spacer which is the equivalent of et29. 9j but on 235 Tyres would push out the tyre another 3-6 mm thus making et 30 look a tight fit.

I'd be going for et35 front if you wanted decent road wear. This would give you the look of standard whith 12mm spacers fitted

on the rear et15 is perfect.

Just be a bit careful working out the offsets if you are using sane Tyres. For example 235/35 up front on 8 to 9j rims will have a similar width irrespective of the rim size as the tyre is still 235 wide. You def won't get an inch difference in width

my 18x9.5j fronts et37 arrive this week. Mine are running 265 all round so it will be very tight fit and I'll probably have to space out a little. Unless you can trial fit it is better to have bigger offset as at least you could add small spacers if there is a clearance option.

ok cheers Shimmy, looks like I will be going for the et35 at the front then and stick with the et15 for the rear.

You are running 265 all round holy sh!t that's wide for the front? What's the benefit?

I will be using these wheels to drive to and from the track so think 265 on the front on the road will be a nightmare!

**cantfind1** · 16-03-2010, 05:55 PM

BTW Shimmy who are your new wheels made by?

**shimmy** · 16-03-2010, 08:04 PM

My new fronts are Volks

I know it is gonna be a tight fit but ihave run et27 9.5j fronts at -3 cAmber so I am hoping """" that with the careful offset choice I Can run with -2 camber to get me there and back

265 all round should allow mr some extra front grip whilst also double tyre life : fronts wear edges and rears middle!

@cantfind1: Ive come to the conclusion of running TD 18x9J ET30 all round with a 10/15mm spacer on rear with 4x 265/35. This allows me to swap wheels/tyres, keeping spacers on the rear giving the equivalent of ET20/15.

30 is too much for a 9 IMO, standard M3 rears are less than that (ET27 I think?) and work fine all round. I think et25 all round with a 10mm spacer on the rear should be fine for a road car?

Nath what issues to do see running ET30? TMS run ET30 all round with no problem on their Cup Cars.

_Nathan_ · 19-03-2010, 04:00 PM

I thought he said on anyother thread that they ran 20 all round?

We know that standard BMW rears all round work and they are ET27, I don't see the point in narrowing the track when I'm pretty sure the extra 2mm either side would be ok with a track camber anyway?

When I said too much I just meant that it is more than I think you need, not that there will be problems (no idea on inside clearance but I suspect it'd be fine as I don't recall the rear 18" m3 wheels being that close on the inside).

Your right he did quote that they run ET20 but he corrected himself when I descussed to him about offsets, as I would have thought ET20 would stick out the arch a lot. As the 18" Rear M3s are ET26 and when trial fitting I found they stuck out quite a bit, but work no problem as some do run rears all round. ET25 all round would work fine too and when adding a 10mm spacer to the rear would = to ET15, which is a good compromise too IMO.
