35 series will require fender liner massaging for turning, 30 series will not. 30 series will look short though for sure.

So I've already got a pair of 18x10 et25 and 18x11 et44. I'm considering adding a second pair of 18x10 et25's for the flexibility of running either staggered or square and just having a few spare wheels/tires with me. Has anyone run or would it make sense to run 18x10 et25 square with Pirelli DH 285/645-18 (not my PR setup but more for allowing some flexibility). My other thought is to just always bring spare tires with me which I am starting to do anyway.

Once I use up the A7's on my staggered set I'll prob sell them for a set of 18x10.5 square so I have two identical sets. I 'm with you on that one!

Hi Gents, I’ve been looking at available tyres to pair with potential wheel setups. As this will be mostly a road car with occasional track duty, I’d like to run something like super sports or 4s mostly. Perhaps one day I’ll have a dedicated track set on which I can run appropriate tyres...
Anyway, now I’m thinking of running the below wheels with Michelin pilot super sports, but I need help with offsets: Front, wheel 18x10 ET???, tyre 275/35 R18 Rear, wheel 18x11 ET30 ???, tyre 295/35 R18 What do you guys think to the suggested rear offset at ET30, and what do you suggest for the front? Regarding front, any spacer or negative camber required, depending on suggested offset? Thanks!! |

Front ET20
Rear ET44 If I were going to go with something dual duty I would look at 18" front / 19" rear setup so you can run one of the "extreme summer tires" Bridgestone S007A, Hankook RS-4, Yoko 08R, etc... It's not common but you can run 305/30/19 rears and 275/285 fronts. If its 95%+ road though the MPSS are hard to beat as road tires.

I'm in southern cal, so not much rain here. Probably not the best judge of that!
On the track though the extreme summer tires are significantly faster than the MPSS.

I’m in the UK, and up north, so polar opposite of your weather ha! I’ll have a further think on your 18/19 suggestion, over 18’s all around. Thanks for the offset suggestions too! Have a great day bud

Did you ever try 19x11 up front with the 305s? It would be great to be able to run 305 RE71Rs square. Also, 295/35-18 vs 295/30 ... most people (including Apex) reference being able to fit 295/35 up front. Do you recall where you had issues when testing? |

It rubs a bit before full lock. The fender wells have a bit of an hourglass shape to them and it rubs in the middle of the liner. This can be massaged with a heat gun and some work. Once massaged the rubbing is gone. I ran then for a full day autocrossing without rubbing. It's an "extreme" fitment but does work.
19x11 doesn't work without a ton of camber (4 degrees+) I do have those to try and it just sticks out too far. The 305 Pirelli slicks everyone talks about putting up front isn't as wide as a 295 Hoosier A7 btw. I've tried just about every combination I think There should be a post on this in this forum.

bracer hey do you think 18x10.5" ET40 with 295/30/18 semislicks square setup (with 20mm spacer in the front) and stock suspension and stock alignments would rub? Or should it be ok?
Track day use.. Thank you in advance.. |

It would be close. If I was to guess I would say it would rub. I think it would clear the strut but with no camber up front I think it's pushing it. it might though, just don't know.

Great fitment, you can fit any tire that realistically fits in this platform and allows rotating |

Edit/add-on: do you or do you know anyone who runs MPHAS with this setup? I'm thinking of keeping my eventual F80 on stock perches at first due to road conditions, but I'll have my MPHAS on hand if I want that installed. The only issue with it (and KWHAS) is it definitely reduces clearance. If I do put them on, I'll probably be running max height and just use the perches/collars for corner balancing only

With my ET36, I can use a 12 or 15mm spacer with zero problems. That leaves me at effective ET21 and it still fits the outside portion of the fender |

Just ordered a set of Titan-7 forged T-S5 18x10.5” +34 offset to run square 295/30/18 … Front will have a 15mm spacer. Running MCS coilovers with 60mm spring setup.
I’ll fit it to another F80 with OE style lowering springs and report back on fitment Last edited by silverbackf8x; 11-23-2021 at 07:20 PM.. |

cool, lmk how it fits. I ended up going 18x10 et25 square with 275/35 but may move to 10.5 square to take advantage of 295/30 in the future. Also running MCS with 2.25ID springs (w/ helper) have the perch about half way in the threaded portion of the strut body. thanks.

How wide in inches is a single 305 Pirelli? Contemplating how to transport track wheels to the events. Would like to use a cargo carrier over a trailer. |

Anyone here running 295/30/18 square with MCS + 6" front springs? Just wondering if I'll need to swap on 5" front springs to sit above the tire/wheel.
