Apex 18x11 amd Cortex offset struts, spacer requiered?

[Mad Hatter]

This week will mount my P2000 Conti 320/30-18's on the Apex 18x11 et52 wheels. Hope they fit ok with my 15mm spacers!!

As was quoted earlier in this thread, I have run the BFG 315/30/18 R1S square with offset Cortex struts and a 12mm spacer and 2.8 neg camber on Apex 18x11 et52mm wheels. Without steering stops, the BFG 315/30/18 tire can rub/wear the fender liners. I am now running slightly wider Hoosier 315/30/18 A7 tires and I increased my front spacers to 18mm spacers. At this point, you may as well go with a 20mm spacer as the extra width allows for use of a hub centric lip on the spacer. The rear wheels and tires are fine with the Apex 18x11 et52mm wheels and Hoosier 315/30/18 A7 tires.

Thanks, just in case I ordered a set of 20mm spacers from Optimum Performance... was pretty sure the R7 in 315 would fit with the 15mm spacer I have, but the with the 320's went for a little more space.

Looking forward to seeing how those big Conti's fit on the wheel and what spacer ultimately is needed. Will be very useful info for everyone moving forward. With as big of tires as you guys like to find, sounds like we need to look into 11.5" and 12" options.

Someone mentioned 11.5" wheels earlier... our SM-10 is going to be available in 19x11.5" ET 56 through the Group Buy. With some persuasion and slightly thicker spacers, I imagine someone could get it to fit the front with minimal poke, however we have not done any testing of that internally.

Absolutely!!

Well got them on today and with a 15m spacer, have enough space to squeeze my fingers thru so we are good to go!



The 320/650-18 Conti tires pock out just a little bit..

If your fenders are rolled, you can go up to a 25mm spacer. Will give the car a little more front grip, too.

Those are some big tires! Looks great however, and nice to know about the spacer requirement.

When are you taking these on track?

My bad, sorry, correction... I calculated badly... Still in second behind a pro shop 800 kg honda with 250 whp

What's the opinion of width on the Conti's vs say a 315 650/660? or so 18" Pirelli on those rims? It might be a 680, I'll have to research.

Liked the 650 after the 295/30-18 R7's which is less then a 640!! I was worried about the wear on the edges of the 320/650-18 but the tire wore evenly.

Interesting, we have a 67 mustang that has the full cortex setup and he was running square with 335/30-18 R7's on 18x12 rims.... His first impressions of the 320 where very good.
