Our 19s will likely clear the GTS kits fairly easily, but which specific kits do you have? Specs for essentially all the brembo options can be found here: https://www.racetechnologies.com/pro...?vehicle=10958

380mm front and rear are what I see most commonly with F8X customers, but Brembo's range is large and I like to know exactly which brakes you have.

We don't recommend any profile 4 fitments for the F8X chassis mainly because wider wheel fitments on these cars need relatively high offsets to be an easy direct fit. With that being said, I'd recommend 19x10 ET25 front and 19x11 ET44 rear pending your feedback on the brakes. These are still profile 3, let you run a ton of tire options and are available in all 3 forged designs included in the Group Buy. We also just hit the Max Discount of $400.00 off on that deal if you're interested in a set with the lower price now guaranteed.

Tom,

Front & Rear rotors are 380MM. So for 19x10 ET25 front and 19x11 ET44 rear, I don't need to put any spacers in the front correct?

Thanks

Correct, the brakes will easily clear the spokes and barrel of any of our wheels in these sizes. No Spacers are required for the brakes. The only reason you might need front spacers is if you're using a coilover (KW, some Ohlins R&T, Bilstein) or HAS kit that limits inner clearance around the front struts. If that was the case I'd recommend a 5mm front spacer with the 19x10 ET25s or our 19x9.5 ET22s if you wanted a spacer-free front wheel option.

The 19x10 ET25 will clear OE suspension or coilovers with good inner clearance without issues. 275/30-19 & 305/30-19s are the tire sizes we recommend with those wheels as well.

I forgot to mention that I have the MP Has Kit and not sure If I need the spacers in the front? Thanks Tom!

Yes, with the HAS kit you'll likely need either the 5mm front spacers or you can run the 19x9.5 ET22 to give more inner clearance without the front spacers.

Perfect! For 19x9.5 ET22, what tire size would you recommend for the front?

Thanks for your help!

275/30-19 can still be run on the narrower wheels especially with street tires that are a bit narrower than aggressive track tires. 265/30-19 can also be run on these wheels as well. Some of my customers opt for a 265/35-19 for some additional tire sidewall height but the taller tire can scrub your fender liners a bit when turning lock to lock or under compression.

Tom,

Is this true regardless of height? I don't have an aggressive drop with the MP Has and in the recent group buy I did the 19x10.

I prefer not to run spacers and if I need to change to 19x9.5 in the group buy, I will do so.

Generally speaking yes. I've seen some customers running narrower tires at the max height the MP HAS kits allow clear, but the perch and spring collar assemblies take up a decent amount of room on the inner edge. I advise most who have this setup to buy 5mm spacers or the 9.5 ET22. If its the ongoing Group Buys you can edit your pledge at any time prior to the deal ending via the "my deals" page on gangup without losing your allocation or spot in line.

19x11 for the rears will fit w. no spacers?

[Blue Angel]

This is a 275/35 Indy 500 on a 20x9.5 wheel. Square, just a slight stretch.

What front lip is on that car?

Yes, our 19x11 and 18x11 ET44 wheels are specifically designed for the rear of the F8X chassis and are a direct fit with 305 section tires. We have a number of examples of these wheels with an ET44 offset on our new galleries:
M3: https://apexwheels.com/gallery#fitme...e=BMW&model=M3

M4: https://apexwheels.com/gallery#fitme...e=BMW&model=M4

Not every gallery shown above will have an 11 ET44 in the rear but most of them do and can be used as a reference. click into each specific gallery to see detailed specs on the wheels.

I actually don't see mods notes on our usual sheet for this car. I'll hunt around to see if I can dig up this info but for now I'm not sure.

Not sure why, but the links above aren't working, these might be better options:

Makes sense. Any pictures on a car or the wheels itself?
