iX wheel thread

yeah, but nobody is going to be racing an E30 ix in One Lap of America. :p

For AutoX, not being able to heat up the tires is a problem. I hadn't thought it would be a problem for a car as heavy as an E30. That's one I'd heard of more in association with 1200# open wheelers...

It's much less of a problem for any event like HDPE or a more formal TT involving more than one lap. In a campaign like One Lap of America in which the operating philosophy is "Use one set of tires as efficiently as possible" having more rubber available to remove before the tire is toast makes the difference between finishing and not.

I'm not talking about cutting fenders up. I'm talking about turning a late into an early. My car already has some poorly bondo'd damage to the right rear quarter panel anyway, so I might as well both fix it the right way and do an interesting mod to the car at the same time. (That is definitely *NOT* to say I won't roll *THE* *SHIT* out of them, however...)

The idea that big tires being can do more work relies implicitly on the idea that the car's suspension can put them to work. This is not a foregone conclusion with an E30, but I have ideas for how to fix that.

[nando]

Yeah, I'd need pre-facelift arches, which may still be available from BMW.



Big tires do more work(TM) ;)
I just fit 18x9.5's with 285/30's on my Fiero and think I can go 18x10.5 with 305/30's with just a little work to the struts. I don't believe there's such a thing as too wide.
What really makes the higher wheel arches fit is the camber curve of the suspension in combination with ride height. The fenders aren't any wider, but if the car's not decapitating grasshoppers and has a decent alignment at static height, then the rear suspension's camber change will pull the top of the tire in more as the suspension compresses.

Ok. Ive done the big tire thing on the E30 - more weight, more cost, less responsive, marginal increase in grip (especially if your tires are cold because you can't get enough heat into them).

Cutting up your fenders in a misguided effort to run "big tires" when you can already fit more than enough is silly.

Now if I could only find some 16x8's with et30 that wont break the bank :roll:

Might have to go with a 15x8. Just wanting something that will fill the wheel well better without lowering it a bunch.

Those stock prefacelift ix plastic wheel arch are little different then facelift, there is that inner edge little different, also there is little lip what come down, also that attachment point is a different place, if you compare facelift plastic wheel arch.
When i was also test fit those 23mm adapter in back this car, it need way more less heat/rolling to get those tyre under that plastic edge.

not worth it IMO. you can fit plenty of tire in either one, more than an E30 needs realistically.

Interesting. My car has some right rear quarter damage and I've been musing about getting early quarters installed so I could tuck wider tires.

Thanks, yes that is little too much in front it need narrower adapter at front, also i try maybe in back to level that difference :)

[nando]

nice ix, but the wheel fitment isn't great. that's like ET0 :p

[litu]

I dont have clue what is that stripe point in there..I was bought as such it is

[Kershaw]

Isn't the stripe supposed to show where the driver is sitting?

[litu]

Yes, it is 1986 prefacelift model, my dream car, same as in my sig

[The Dark Side of Will]

So that's a pre-facelift? Is that the '86 in your sig?

[litu]

Here is my new ix prefacelift..16x8 et20, front there is adapter 20mm, tyres are 215/45-16. I dont know those spring, but stock shock absorbers.
I was roll little those front plastic wheel arch, also there was little rubbing in there m-tech I bumper corner, but i was showing some heat there.
At the back there is not adapters, there is made that same thing as was that my red ix, there is those rubber pad to stiff that spring little.
In this prefacelift-model has little more room in those arch then facelift, also those plastic wheel arch is better then in facelift model

PS, those rims are Rota grid-v, they are meant for frontwheeldrive car, so i need put at least 20mm adapter in front to clear those front brake caliber rack hitting those rims spokes..I will try some day 15mm adapter in front also it need at front because it looks silly now, then that front is way more wider then back, i was thinking like 15mm also.






Pss, sorry for those big picture
