Stagea Wheel Dimensions?


Recommended Posts

fronts would probably fit with

7mm less clearance from strut and 43mm extended outwards

but the rears are gonna be

29mm less from strut and 59 mm extended outwards

for reference

17x9 +37 had about 3mm of clearance to stock struts

so i'd say you'd want a 15mm spacer on the rear (about 13mm more inset than the 17x9), maybe 20mm, but then you'll probably be poking out the guards

and as said before, you need the same tyres all round

so stretch 245's onto the 11's or run 265's on the 9's (latter is probably better)

the different rotational speeds

ecu sees rears going faster/slower than the fronts and tries to help you out

Then its welcome to surge city!

Mine was doing when one of my rears was slightly more worn than the other

It's rolling diameter !!! Tyer wear would not be enough to trip it, currently I run staggered sets on all my stagea's but as long as you run close enough to the same rolling diameter you'll have no probs

Example 1 19x8.5 and 19x9 running 235 40 18s all round

Example 2 18x8 with 225 40 and 18x9 235 40

Example 3 18 x9.5 with 235 40 and 18x10 265 35

Plus I've had other sets on the car that have all worked out with no surging . Like I said just get close as with in rolling diameter and you will be right

To be honest i think its fine as long as the rears are bigger than the fronts

100% my atessa gauge was creeping up when on the highway (nearing 10 on the gauge)

I changed 1 tyre and its fine now

Also the car was surging at 100km/h

I found this - had 2 tyres replaced on the front for RWC and got some serious surging issues - chucked them on the back and its aok

tyres dont need to be the same just the rolliang diameter does :)

Ok so using the pirfect wheel specs for an Rs4S

18X9.5 +12 all round

what tire profile do you recomend?

i will most probably roll the guard lips for comfort, i just want it to tuck in nicely, obviously beinf 4wd the front and rears need to be the same.

Running 18 x9.5 x15 with 235 40s upfront and 18x10 + 15 with 265 35s on rear with rs4s cradle see how that goes they are the same rolling diameter

might get a mate to fit a 235 on on, see what the stretch is like, still unsure of brand so it will depend.

coilovers arrived otday so gonna drop it and see what sort of cavity im looking at

ok i seem to be getting idfferent information from different wheel calculator sites, can some one help me out with some dimensions.

CII Rs4-S c34

it currently has R34gtt wheels fitted which i beleive are

17X7+40

as they are from a RWD R34 they sit quite far in the guards.

just fitted my BC coilovers and when going over bbumps when the wheel cambers in the rim touches the coilover thread.

static it is a few MM off.

its the rears which are touching on bumps, the fronts are fine.

i am going to use maby an 8-10mm spacer to solve the issue but the new wheels are on they way and im confused as to weather they will foul aswell.

they will be

18X9.5 +12

one site sais i will loose inner clearance and another sais it will gain so im not sure.

The wheels should be stamped with their size somewhere inside them, they usually are. I'm guessing they're +30, not +40 offset. An offset of +40 is usually for FWD cars.

Are you using an online tyre calculator? There are plenty around if you do a Google search.

well they are R34 GTT stock wheels which from searching on SAU seem ot be +40

i am using online tire calculators which is where im getting the conflicting information from.

does anyone know of one which they would trust?

had the exact same problem, but both my rears where bold and my front where 95%, and started surging aroudn the 90km/h mark, and the gauge had about 10% i removed the plug under the dash that brought the 4wd light on and limpt home (130km's)

    • thanks for heads up on actuators - will sort something as back up or solution as yes dont need that have enough trouble but no doubt some addition of something to spares boxes is required yes have a clue about WTAC but nothing has been officially put out yet so will wait to see exact details Pro class is, has been and will become a draw card for lap records and one off builds for show and thats about it I think - be interesting to see how open they make it Pro am is the old Pro in reality Open class will be split into 2 with slicks and 050's with no doubt slight variances in allowable drivers and changes in aero Clubsprint + apparently a true street class   They have to and are refreshing it all and bringing things up to current standards and need to 100% adhere to rules because whether people like it or not / or say it or not - for alot of competitors it is sheep stations and has been for a while when Im getting told I was illegal because i cut my rear bumper too high and yet others where in the grey areas of legality with everything from engines, suspension, ride heights and more serious influences it actually got quite out of control and heated this year so as much as I may be impacted by some of the changes and prob spit the dummy when I have to spend money changing things I think its a good thing for all

    • Start with a multimeter, and see if you're getting power at the TPS. There should be a manual for your car somewhere on these forums and it'll have the info for what closed TPS signal voltage is, and how it should sweep to full throttle. Same as for other sensors / valves.   Have you checked things like your base timing etc? See if anything looks amiss there too?
