Fitment on a NA for Work Equip 03's

[broady]

Whoa, you painted your car again?

Looks great!

[bowzaa]

Ahh cheers mate, guessing the fronts are 7's by the semi-mushroom type look with 185's?
How low are you running the car now?
I'm at ~60mm from rails, and are just debating what tire/wheel diameter i wish to run before they get built.
Car looks good!

[bowzaa]

Wow that is low, i can still get my factory jack under, although just.
Thanks heaps for the specs mate, much appreciated, car looks ace!

I guess I'll necro this am I'm having a few questions regarding this as well. I currently have 15x6.5 wheels and 195/50 Kumho KU31s on a 90NA6. I'm looking for a wider stance, but without needing to roll the fenders, so maybe x7 or x7.5 width? I've emailed Work regarding the 15" O-disk, and they've claimed that an O-disk won't fit due to brake clearances. They've quoted me:

15x7 +10 with deep dish 57 mm – AU$ 1900 delivered
15x8 +22 with deep dish 57 mm – AU$ 1880 delivered

Would the 8" width be too wide? And what's a maximum offset that I can take with each width? In the 2nd post broady wrote up some sizes:
x9.0 +33
x8.5 +26
x8.0 +20
x7.5 +14
x7.0 +7
x6.5 +0
x6.0 -5
Are these for O-disk or A-disk?

I'm more than happy to help with fitment questions, and I'm not trying to be a smartass, but why would you want "fitment" without wanting to touch the gaurds? That's like saying you want performance increase but don't want to take out the stock intake/exhaust.

Just roll the gaurds, it's nothing to be scared of, then you don't have to worry (as much) about rubbing and clearance.

"Don't roll the guards, you will ruin the perfect body shape of your Miata and destroy it's remarkable handling characteristics. If you need advice on wheel 'fitment' (stupid kids- move to club roadster), my advice would be to keep it standard or look for nb8a oem wheels as these are manufactured in the highest quality by Enkei for Mazda. They sit slightly wider to 'fill' the guards on your car and will give you a modern look. If you were to really do something crazy, I recommend getting some Chapparals which are available from Rspeed. They are available in some in some pretty ridiculous sizes such as 15x7 +38 this is 2" wider than oem standard na wheels. Although the steering will be significantly heavier than standard, you may have to convert to powersteering."

My advice if you are after something flush, it depends on what tyre size you want. You can't go too wrong with 15x8.5 +5 with 195/45/15 ku31's. They sit really nice with a fair bit of camber and a huge height drop. You will have to mod your guards regardless so don't worry too much about it. You will need a pull too for this but like I said, don't be afraid. They are supposed to be ruined

LOL! Gold!

I would like it corrected to 90% instead of every member... I suppose the point does get across, rolling you guards WILL ruin the handling.

[emily_mx5]

you were just quoting morlock right nanotech? i lol'd.

why on earth will rolling the guards ruin the handling? it is literally folding a piece of metal so it sticks upward instead of outwards.
or am i missing the sarcasm ?

[Mr nanotech]

"It throws out the aero and changes the total downforce to the car. Folding them out will act as air brakes and negatively effect the your turn in and straight line speed" - Cartalk guy

hahaha so good

Would that big of a stretch from the tires reduce grip or increase wear?

Also, would an O-disk fit with stock brakes in a NA6?

[Mr nanotech]

Yep O-disk. I have 15x8 -6 O-disk cr-01 on my na6 and upgraded to nb8a brakes all round without any issues. 195 on an 8.5 idnt a huge stretch to be honest. It should be fine.

At the risk of drawing the ire of stance fans, both state governments and CAMS refer to the Tyre and Rim Association Manual with regard to legal fitment of tyres for registration and for competition. The manual describes the range of tyre profiles suitable for each rim width. If you choose to ignore this (and a large number of stance enthusiasts do) then you could negate your car's insurance, be defected and be knocked back in scrutineering for a CAMS event. 195/50 on an 8-8.5 inch rim is not acceptable fitment legally, even if it is tucked within your guards.

Can you do it? Of course, it's your car. Will it look good? Beauty is in the eye of the beholder, but a lot of stanced MX5's look fantastic at rest or at low speed IMHO. At normal driving speed they begin to look silly - bouncing off the bump stops and crashing into potholes, and are probably not particularly safe because of this.

My aim in modifying cars has always been to improve performance - looks come second for me, and I wouldn't compromise performance for looks. That's just me though. I'd be fitting 225 or 235/40 tyres on an 8.5 inch rim, adding some guard flares to cover them and reveling in increased grip.

[zephyrus17]

Would you have a link to that specification. I'm quite worried as well about legal issues and with insurance.

[emily_mx5]

lol dont mod the car then. nearly zero modifications are legal.
If they are done within adr's they still have to be authorised by an engineer and mod plated.
