Second track day in my 135i

[Mtl135i]

Any suggestions for a dedicated wheel and tire package for the track only

Thanks

At St-eustache yesterday? I go usually but got some problem this weekend at sanair. Cool pics.

St Eustace on Saturday with the BMW club of Quebec.

Had one 20 min session at sanair 3 weeks ago. Fast track.

Depends, how much track experience do you have? And do you plan on driving to/from the event with your track setup or will you swap at the track?

If you're still relatively new to it, I suggest you stick with good street tires as R-comps may cover up your mistakes. And if you're driving to and from on this setup, again I recommend good street tires like Star Specs, AD08, or RS3s. If you're pretty experienced and plan to swap at the event, R comp is your best bet... NT01, RA-1, R6 all solid choices.

APEX makes pretty good wheels for this. Cheap, light, and disposable.

I just bought apex wheels and rs3 for a track setup.

Apex ARC-8 is currently the best fitment. Looks like the new Apex EC-7 might fit even better in rear, not sure yet.

What is better: square set up or offset?
(I know that with square you can buy 5 wheels and rotate, but is their any loss in performance?)

Square with aggressive camber in front. Here are the available sizes. Beware the widest fitments require some modification like front camber and/or fender rolling:


This is a staggered EC-7 setup on a 1M:


The BR Racing 135 with ARC-8s 255s all around...I think:


This is a forum member's 135 with 8.5s w/245s front and 9.5s w/255s rear:

Berk uses our v701's a lot of the time on their track-days.

Square and offset two totally different things. I think you mean square vs staggered. Square will result in more neutral handling but most people don't realize that shoving as much rubber up front is useless if you don't dial in enough camber for better turn-in, else you'll just be plowing through the turns with all that extra rubber.

Offset measures how close/far the wheel mounts to the hub. The lower the offset, the more aggressive the fitment (the further it sticks out). But it's all about finding the right offset where it's not so far out it will rub fender side, but not so close where wider tires will rub strut side.

Yea but what's the weight on those? I remember the V710's were ridiculously heavy.

[OLEK135i]

Yes I meant square or staggered?

VMR 710s

• 18x8.5- 23lbs
• 18x9.5- 24.5lbs

From the **********s site. It's heavier than the ARC-8 by approx. 4.5 lbs. per wheel.
