Versus Gripp Wheels

[OMY31T]

ok so how does a set of Volk GTC's sound that are 19x9.5 +11 and 19x8 +11??? should work?

[pipster11]

could end badly

the attessa is sensitive enough to play up with worn rear tyres, so running a staggered offset you's have to get tyres that are really close in rolling circumference/diameter

offsets would probably be ok, is it for an auto or manual? i forget now

[OMY31T]

its a manual, and after using a rolling diameter calculator, icame up wiht the following.

these are the wheels combos.

19x9.5 +11 with a 275/30 tyre, overall diameter = 647.44 mm

19x8.5 +11 with a 235/35 tyre, overall diameter = 646.93 mm

so they are quite close, if i sit down im sure i can work out some difference in pressure to bring it even closer together.... the attessa isnt that sensitive is it haha... 1.49mm difference.

[lilcrash]

YES IT IS THAT SENSITIVE. YOU ARE NOT LISTENING. Having a slight flat tyre is enough to set off the attessa, just but wheels in IDENTICAL sizes. It's not a hard concept.

Actually no. Just ignore my post again. I want you to f**k your car, maybe then you will listen.

so to get this correct in my head for when i finally buy a decent set of rims. buying rims that are different widths (ie 8.5 and 9) with different width and sidewall height (ie 235/40 and 265/40,35 or watever) will f**k it up but if i get both as for example 19 inch by 9 inch with 245/40 tyres but have the fronts as +22 offset and rears as +11 offset won't. Ignoring the fact that i've pulled these numbers out of...well you know where as far as if they will fit in the guards. The fact that the only difference is the offset means they will work....yes? because the only difference is how far the outside of the rim sits from the hub?

[OMY31T]

sigh, dont post if you have onthing imformative to say

the reason im asking questions is because i need answers, otherwise, my car would have the wrong wheels by now, there no need to be a wanker. i understand the rolling diameter issue, thats fine, i just want to see how sensitive it is. now whats wrong with changing the tyres.... couldnt i just run 245's all round, im pretty sure u can go down to 235 on a 9.5 inch rim??? so a 245 should be fine, but it would be stretched on the 9.5 so again would that change the rolling diameter???

how are there others running staggered offsets?? ive seen other stages with it done.

thats correct, you can run different offsets, but not a different overall rolling outer tyre diameter. the problem ive got is finding somthing unique in my budget that suits the car

[lilcrash]

Off sets don't matter, just rolling diameter, I have 18x8 with +35 fronts and +6 rears on my rs4s, I didn't realize that the manual needs same offset front and rear and the auto needs staggered offsets when I bought my rims. I'm putting 30mm spacers on my front rims when I get the time.

ok thanks. i now know what i need to so i'll but out and let u guys have fun

[OMY31T]

f**k it, i decided to buy some KOYA Endless rims. 19x8.5 and they are blanks so i can choose the offset i want. $290 a rim with whateva offset i desire.

so, to make it simple, what offset should i run all round on 19x 9.5's on a RS4S to have the wheels sit just under the guards in the rear without pumping the guards. i will most likely buy 245x35's all round for the rubber.

lol im sick of hunting, its easier to get somthing made.

thats them. offset from +6 to +45

[OMY31T]

got bored, i guess they will look somthing like this.

btw i made a typo above, just to confirm they are 19x8.5's not 9,5's

[OMY31T]

ok i have decided on tyres aswell now.

so ill endup with 4 x 19x8.5 and +offset??? with 235/35/19 tyres.

[lilcrash]

By my measurements. A + 9 will sit the same as mine, but I'm at stock height and my rims would probably tuck into the guards dropped. So I'd probably run a +6.

[OMY31T]

but at +6 will they still tuck under the guards when it is lowered?? i basically want the top of the rear tyre to just tuck under and not scrub out on the guard.

[lilcrash]

Yer a +6 should be about right then, although it will depend on your camber settings. On my car if I lowered it a +6 is perfect.

[OMY31T]

ok no wories, i hope ur right hahaha.... otherwise i will be wasting over a grand

going off a calculator this is what ive come up with

from the stock 6 spokes which are a 7" +30 offset

with a 19x8.5 at +6 offset

i will have and extra 5mm clearance on the inner side

and have a the wheels 43mm wider on the outside.

that sounds right, because as u could see in the original pics, that the wheels sit in quite a bit. so 43mm should bring them basically inline with the guards. but im just wondering if i should go a bit higher in offset to be on the safe sifde because i dont want to get them and not beable to lower the car, and i will more than likely put in some adjustable camber items to fix up bad camber from lowering, so i think i might go a +11, because i know for a cact i have 5mm extra on the inside of the wheels from where they fit now, so the inside will be sitting the same and the outside will be 38mm wider, whcih should give me a few mm of clearance for camber correction.

[pipster11]

just remember, you can always machine metal down, but its hard to add it back on

[lilcrash]

Yeah that sound fair, but I agree with pipster. Most places can take a few mm off if you need it.

[Raysboostin]

i wouldnt go +6, u will almost certainly have clearance issues once lowered. anywhere between +10 and +15 would be the go. ive got 18x8.5+23 on mine and they could use a 5mm spacer, but im not gonna use 1 cos its illegal.
