949 Racing 6UL E30 Spec wheel folks - QUESTIONS.

[tinoe30]

We have been using 949 6UL Spec E30 wheels (15X7) and love em.
They are just over 13 lbs each, have 2 valves and a design that avoids damage to the valve stems or spokes when there's wheel to wheel contact.
The Spec E30 suspension lowers the car quite a bit hence we did hammer the rear fender inner lips. Not needed on the front.
We run a 10mm spacer in the front.

So here they are on our NASA Spec E30

I have a tire machine so, I can change tires. Majority will be street use and with the occasional AutoX, I will change the tires. On a 15x8, the tires for race use are plentiful. But A/S tires are hard to find in that size.


I think I will stick with the 15x7, but wonder if guys are rolling fenders to allow these to fit well with a setup like I am using. I am on Koni adjust with H&R race springs.

You would not need to roll the fenders with 15x7 +15 wheels. You would also not need to roll the fenders with 15x8 +26 either (assuming you ran a 10mm spacer with the 8's, and 225 tires).

You can still run 205s on an 8, so the point about not being able to use all seasons is kind of moot. There is no reason to get 7s when 8s are better in every way.

My 205 star spec 2's have way more traction than a stock 2.5 can over power

If you want to be faster in autocross, get 15x8's and Hankook rs4's 225/45

Kuhmo ecsta at in 225 50 15. I had them on trm c1 15x8 and it was a nice setup

AS tires for autocross aren't that great. Get a 200 treadwear RS4, get studs and and metal hubcentric rings.

The issue is the tires for street use. Hard to find an A/S tire for the wheels. I want to change these if and when I do an AutoX, etc. But, when not doing that, I want a good A/S tire.

get the tr 15x8 et 20's. they fit without a spacer and you can run 225

The offset. If you run the 15x8, the offset is such that it will not clear properly. It's a +36ET. The 15x7 for example is a +15ET... The 15x7 is specifically made for the E30 and the spec class. It's a bolt on and go wheel...



Again, spacers aren't an issue. but you'd need a set to compensate for the offset...

Got it. If I absolutely wanted that particular wheel, I'd go with the one that's the bolt-on fit (15x7). Hassling with spacers and hubcentric rings when changing or removing wheels frequently gets old fast, especially when they're hot.

If you haven't already, check out the Jongbloed Racing Wheel for SpecE30. It's more or less identical to the 949 version, but available in silver and costs less.

I still don't understand why only the 15x8 wheel requires a spacer...? Or does that apply to the 15x7 version as well?

Tons of people run spacers on track and autocross. Just make sure you have good studs that are the proper length to accommodate the spacer you run.

Agree 100%. However, the tire choices at 225/45 vs the 205/50 is harder to find an A/S one for street use.



What spacers are you all running with this brand if using a 15x8 wheel? And, again... are you having to roll the fenders?
