R33 Wheels DONT FIT..... F**?

[joetheeskimo]

I bought some R33 GTR wheels 9J ET30. Put them on the car and they dont fit, they stick out the arches by 20mm. Ive lowered the car with lowering springs so have about 20mm arch gap as well. What are my options, can i get camber adjustment. My cars a PFL Legnum

[crazydriver81]

Cambr adjustment will not work - not for the amount you mentioned. 8.5 x 18 Offset 35 is the max you can fit without stretching tires. If you are going for 9 inch wide wheels, you need to stretch tires and need to roll the rear arches on a PFL - but even that is no guarantee that the +30 offset will fit then.

If I were in your shoes, I'd sell the wheels and get some nice Evo 17" alloys in 8x17 Offset 38 - will fit and does clear Brembo calipers, should you wish to upgrade later on.

How can these wheels fit on a facelift.

Do the arch extensions make that much of a difference.

Also camber should work just run -4 to -5 degrees all round

Put up some photos of the wheels

change those tires,put some 225/45/17's and it will work.

[Humpty's Revenge]

Have you checked what it says on the rear of the wheel ?

As that looks bigger than you state

[joetheeskimo]

i dont want to change the tyres as they are goodrich Eagle F1 with loads of tread. the fronts are 235 and rear 255 all 9J. They didnt make r33 gtr wheels in any other size than et30 9J.

[joetheeskimo]

how much width do you gain with facelift arch extensios.

[Humpty's Revenge]

None

There only over arches

[evo1rs]

Just due to the difference in sidewall profile I'd be getting some more 235's to match it all round. Not sure how the 4wd would cope with it otherwise.

[joetheeskimo]

ok well that picture shows how much poke with 235 tyres.
can I get camber adjusters or does the legnum have oem camber adjustement.and if so where is located.

[joetheeskimo]

i lowered the rear a little (probably not in the way most people would suggest)

the wheels are now better. they are sticking out by about 6mm. It has a 5mm slip on spacer as the hub diameter is a lot larger than the centre bore of the r33 wheels.
I now need to figure out a way to bore out the centre bore of the wheels to match the hubs.

The r33 centre bore is 66mm I'm not to sure what size the hubs of PFL are or what PFL hub sizes are like compared to FL, If anyone does know please can you shed some light on this and also shed some light on how i can bore out the wheels to the correct size (or bigger size)


The arches are going to need rolling as they are rubbing on the tyres when i drive it hard, corner hard or doing anything hard haha.

lowering it has given it a slight bit of negative camber, if i can get some coilovers then i will drop it more so they tuck in more.

The 255 are defiantly not going to fit. Only way to get them to fit is to get hold of some FL arch extensions (that extra few mm will help)

Bore size is 67.1 IIRC

[joetheeskimo]

Bore size is 67.1 IIRC

is that on PFL or FL. or do they have both same size hubs

[chris g]

I would have thought that mis-matched tyres front to rear should be your biggest worry - AYC/4WD will not like them...

May result in damage!

As long as tyre radius is the same he should be ok

IIRC pfl and fl share the same bore size.

[crazydriver81]

center bore is 67.1mm - no dfference between FL, PFL, Evo 4-10, Outlander...

[chris g]

AYC/4WD is sensitive to worn tyres and varying tyre pressures so I would not risk my cars drivetrain with the vagaries of mis-matched wheels/tyres and imprecise tyre radius...

[joetheeskimo]

i checked on will they fit and it says that the standard coty wheels and my r33 wheels have the same rolling radius within 1.9% of each other.

[horndog]

I think the comments above are more aimed at Whats the rolling radius difference of front wheel to back?
You didnt mention the aspect ratio of the fronts (or I missed it..)

The viscous centre diff has been a source of problems with mismatched tyres on some cars, it doesn’t matter if the wheels are 10% bigger, as long as they are ALL 10% bigger

There isnt a 'set' allowance, just that you run a bigger risk of damaging the drivetrain with a bigger difference rolling radius front to back.

[evo1rs]

I agree, eg 45% of 235 is 105.75 mm and 40% of 255 is only 102 mm so a difference front to back may only be 3.75 mm but it all puts strain on the drivetrain.
I'm getting some 9 and 9.5 x 17's soon and I need to work out the closest match or just have the same width all round and hope the stretch difference doesn't make too much. As yours are all 9's I'd get 225/45 all round as previously suggested by rajvr497. It's not too much poke anyway!

[joetheeskimo]

they will all be the same size. Im getting 235 to replace the 255. There is no way 255 will fit.

[CANDEE]

Get the centers of the wheels machined out to our hub size and you wont need to run spacers. An number of the ozvr4 crew have run the r33 gtr rims with no issues at all once they have been machined.

[Louis]

As long as all 4 rolling radius are the same the diffs will be fine.
The 1.9 might knock your speedo out a little :)

[Confused]

My car has been running on 235/45/17 on the front, and 255/40/17 on the back for as long as I've had it, and I've done about 80,000 miles in it.

The previous owner (who fitted the wheels) had also fitted some plastic generic stick on arches, and has cut away the original rear arches underneath them, to allow the wheels to fit. I'm still on standard suspension, and it only rubs occasionally when I've got a very full load and go over some hard bumps.

Guess you run 8's and 9's garry.

Staggered tyres are fine as long as the wheel widths are also staggered and the percentage is within 1-2%

215/40 and 225/40 and half half a J Difference in wheel widths.

[joetheeskimo]

Arches are being rolled tomorrow so that should stop the rubbing. I will try with 255 again but very doubtful as Et25 9J and 255 is quite wide. If 255 rub then ill just get some 235 to go on instead.

[Pugme]

Have u got 255 on the front?

Are the wheels staggered width as well? Or is it just staggered tyres on a set of 9j?

If its staggered tyres on 9j wheels all round id strongly reccommend not driving on them! Lol

[Adam.Findlay]

None

There only over arches

thats the purpose of over arches! you add the over arch and cut the stock metal guard to allow for extra wheel clearance. I know thats not the purpose of them on stock Facelift cars but I have done this when spacing wheels out to fit brembos on before, using FL flares on PFL guards for extra clearance



Bore size is 67.1 IIRC

center bore issue has been covered over and over on OZVR4.com many guys over there using R33-GTR wheels on VR4's over there. some even using R34-GTR 18" wheels too.

[Adam.Findlay]

+1

dont use staggered tyres on 4wd cars. always results in different rolling radii front to rear which is heavily detrimental to the center viscous coupler.

[joetheeskimo]

they are all 9J. Rears are 255 40 17 fronts are 235 45 17. Should be pretty much identical rolling radius.

[crazydriver81]

- 1.2% radius difference (fronts are bigger) - don't know how this will influence the 4WD system though. But you were about to get some other 235's to match, right?

[Kenneth]

With a viscous coupler, it is the equivalent of driving with the hand brake on. Not on a lot, but on nonetheless.

Having different rolling diameters, tyre tread patterns etc from front to back has been covered a lot. It usually doesn't present a HUGE problem in normal conditions, however if you get to the point that traction is a problem, you will be stuffed. Try getting out of a skid with the handbrake on.

[adaxo]

Ok so please tell me I not hurting my car by running the same size (245/40/18) BUT 8.5 wheel widh at the front and 9.5 at the back???

[chris g]

Approximate match from old tyres/wheels to replacements may be ok for speedo working when changing to lower profile tyres on bigger wheels but...

IMO approximate when having different size tyres on rear is just a problem waiting to happen...

...it was ok for miles until it failed...

...it was ok for miles whilst I abused the engine/gearbox/diff until it blew up...

Wider wheels on rear with same f/r tyres AFAIK would be ok but why...

...it stretches tyre and apart from poss legal issues, I assume it changes tyre contact on the road, puts more stress on the tyre structure/tyre wall so must change tyre performance - we rely on tyre wall/stiffness/flex as part of handling response by the car...

...so why bother, apart from the look...

And all that trouble of bigger tyres - less choice/more cost...

[joetheeskimo]

its not bloody stretching tyres. 9j recommended sizes are from 235 - 255 wide. its not like im putting a 165 tyre on 10j wheel. the stretch is barely visible on 235..... if at all.

[chris g]

I think you have bloody misunderstood my post...

My post was particularly aimed at Adaxo and I thought this may have been clear as I posted immediately after his but obviously it was not clear enough...

But my view about 'approximately the same'/'almost the same'/'just about the same' applies to all of us who upgrade wheels/tyres...

Just to make things clear, I don't like the look of stretch tires too (maybe a little, on some German VW polo type car), thing is that wider tires will catch inner wishbone/hub so its a bit compromise between look/potentially drive train issues, plan was to fit concave wheels at the back as IMO is looking good on estate and fit tires wide enough to not been stretched but that didn't work at the end.
