True. Mystery alignment and spring rates are just my first concerns.

18s aren't always boat anchors. Some are reasonably light and it's not too hard to find an 18x8 lighter than stock. But I do think too many people go to 18x9.5s on this car (may not be the issue here).

Either way for this case, you've got to get your alignment numbers and should know your spring rates as well. Hard to help without that.

From Street ultimates down, or up.

Although all are available with different spring rates, it's the valving and dyno work that makes the big difference.

While I agree in theory to everything you said, by making them 18's you just handicap everything. Sure you can try and make them lighter, they are still so massive they are going to be heavy.

Of course for the street I see no reason to run anything other than 16's, but that limit's tire selection drastically because 17's have become standard for so long. I really wish hub swapping was a thing so I could switch to 4x100.

Yes, for lots of cash many companies will make anything you want. Sort of odd to not know that. What were the MCA's on dirtfish rally? $5k or so? Hey that's cheaper than Penske's.

i didn't think custom solutions could be had for under $10k. nice to know now.

True that an equivalent 17 will be lighter than an 18. Also true that after all the preaching I do about big heavy wheels (which is a lot), we ran an 18x8 on our first BRZ shop car and it was almost entirely for looks [emoji38]. But they were relatively light BBS wheels that looked really good.



I also ran 16x7 Enkei RPF1s on our 2nd BRZ which were awesome (also I'm now selling them if anyone is interested).







Dirtfish uses Reiger and I think a custom Bilstein for the rear. Nameless used MCA on their rallycar. It looks like MCA is pretty popular with the rally peoples over here.







Lots of possibilities for custom and/or built to order for this car, at a wide variety of price points. Custom can mean different things to different people, but we can have your Ohlins, Bilstein, JRZ, etc. built to order and custom valved if you like.



Fully custom isn't always better...it depends on the quality of components used to build the shock and the expertise of the person designing and building everything. You can reshim a crap coilover for a custom valving profile, but if you're still using crap shock fluid and a crap piston and crap adjuster/shaft, it's only gonna be (maybe) slightly better crap. But a good custom shock can give you what you need especially at the higher end of the scale IF you know what you're asking or are working with someone who does.



Happy Thanksgiving y'all.

Better question may be...What am I really looking for the car to feel like, to know whether a wider would be beneficial or detrimental?

Sorry new to track days. I have some Tarmec 2's sitting on my shelf waiting to go in this winter. I plan to keep running stock wheels with Hankook RS4 225 for now but after FI I was thinking 17x9. I liked what I have read on the Maxxis VR1 and was thinking probably in a 255 after the SC. (Built engine with 10.1 this winter) I'm going to lose a few horse by staying naturally aspirated this summer but I need to work on my line more than anything anyway.

Sorry to hijack but I though the similar question could help OP.

The RS4 is a good learner tire but I find Hankook's tire compound to have an abrupt breakaway.
