Default 6UL fitment guide

About two months ago I was lusting after some 6UL wheels as my 14" BBS alloys are currently just holding car parts. So thought I could sell one for the other and have shiny shoes.
I went searching for guides and found a few but one was really helpful.
It listed the sizes, offsets on NA and NB and the work needed to get them to fit without damaging stuff.
For the life of me I cannot find that website again. Has anyone else found it?

A good one but not "the one": https://supermiata.com/roll-storage.aspx

We could of course create our own compendium to show the same if no one else can find the site.
Please post a side picture (like this) with car variant, wheel dimension, tyre size, fitment adjustments.
I will keep editing any data i have and amending the pictures for each wheel size.

Car: 1992 NA 1.6 S Limited
Wheels: 15x8et0
Tyre: 195/45/15
Front Adjustment: Rolled and Pulled
Rear adjustment: Rolled

Or go to the actively used 6UL thread which starts at Gen2.
Unfortunately out of 60+ pages (on 22 currently) there are very few statements of "i have this, i did this" I fact most of them don't even state what they have.

Best thread for comparisons I've found yet

Stop it Vlad :P

I think your looking for the goodwin racing site. he seems to have some fairly specific fitment info. either that or just do what every one else as said before me.

On an NA, the biggest I think you can go without surgery I believe is 15x8 et36 with a sensible sized tyre. 15x9s *may* be possible if you are running skinny tyres, roll the arches etc.

As we are UK based, the tyre choice sucks for wider tyres :(

205 50 15s - lots of choice - Federal 595RSRs, R888's, road tyres from the main manufacturers
215 45 15 - Toyo T1Rs, R888s, DMack
225 45 15 - R888s, R1Rs, Dmack
225 50 15 - will probably rub - Toyo T1Rs, R888s, Kumho V70s

If you want to go wider than a 205, you either have to have crap road tyres (T1R) or go for a full on trackday special (R1R, R888 etc) that may not do well in our traditional weather (cold, rain etc) on the road... IIRC they are also pretty expensive compared to the 205s...

On the plus side, with skinny tyres and less grip, it may mean that 4th gear lasts longer than 5 minutes as it'll spin the wheels not shred the gearbox

Have a look at eTyres I've used them since I got the 5. Cheap, fitting is where you want and the tyre range isn't bad.
Although as always ask for the estimator to be turned off when balancing. ~5% is noise inducing. When you do this ask they want a sandwich or tea and they will be happy
Granted I've used them a handful of times but nothing bad to say yet.

Genuinely though having an index of sizes and what was need would be a desirable thing given the information is so spread about. Guess care is lacking when you can just roll and pull regardless

The link to supermiata is now broken even though it did work.
I have included the information from the cached version to help where it can.

I have an odd idea that deep dish rear (et0) and normal front (et36) would look rather lovely.

Code:
Fitments

90-05 Miata

15x7 (discontinued) Race fitment for Spec Miata. 205/50/15 fit no rubbing with Spec Miata suspension. 225/45/15 on ITA car may require trimming fender liner, depending on suspension bump travel.
15x7.5 +34 (discontinued) 195/45 - 195/50 - 205/50 - 215/45 - 225/45 fit standard length dampers no rubbing at all ride heights. 225/45 may require trimming liner with short body coilovers that allow the suspension to compress further than stock. 225/50 require trimming liners.
15x8 195/45 - 195/50 - 205/50 - 215/45 - 225/45 fit standard length dampers no rubbing at any useable ride height. 225/45 may require trimming liner with short body coilovers that allow the suspension to compress further than stock.
225/50: fit NB's fine, NA's require trimming liners and fender roll. 225/45: at least -1.25* front camber recommended for the NA, NB's clear with stock alignment.
15x9 195/50 - not recommended. 225/45: Tires fit NB with no mods needed, fits NA with slightly rolled fenders. 225/50: require rolling and pulling fenders, removing liners on NA, NB only requires slight roll. 235/50 Toyo R888: requires rolling and pulling on NA, roll only on NB, will rub top of tire at full compression. 275/35 require rolling and pulling, removing liners on NA, flat roll on NB. 20-30mm spacer recommended to fill aftermarket flares.

Tire/wheel will not clear stock front spring perches. Narrower 2.75" (70mm) Tein, JIC spring coilovers rub the tire at full lock. 2.5" (65mm) GC's and similar rub less at full lock. 2.25" (58mm) springs have no rubbing. Wheel may not clear front upper control arm when backing up at full lock, double check and use 3mm spacer if you get wheel to control arm contact at full lock/ full droop.

It's well known they fit fine on a 9.

Ride height has nothing to do with whether or not a tire fits or not.

Respectfully disagree. At factory ride height those tires wouldn't have even bolted on. I know its a different animal all together but ride height still matters. Could you explain your reasoning on why it doesn't? We might all be able to learn something.

Miata tires (23" tall) rub the fender tops, shock towers, and/or the outer fender lips at max bump travel. Bumpstop length and shock body length are what dictates max bump travel. If you raise the car 1/4" or 1/2" or 1", it will still hit the bumpstops over large bumps or curbs, and the tires will still rub.

If you take a 4-linked 4x4 and the tires rub when you fully articulate the suspension, raising the truck an inch isn't going to magically make the tire rub at full articulation go away. The limits of the suspension travel have no bearing on where the car sits at static height. It's exactly the same with every car.

Copy that. Just learned something. And thanks for the quick lesson.
