Ask your Rota questions now!

Stiva's running hub spacers with the shakotan's. I'm not sure if it was to fill the flares or to stop wheels/tyres hitting spring perches, but It also cause clearance problems when turning

I did get some pics with post up later. I am waiting to here back from the NZ agent if a number of us here in NZ can get (might have to be special order) 15x8 +10 RKR currently the only have 15x8 ET0 (0 offset) now these ET0 work with non coilovers 240z or 260z but due require rolled lip/guard work. Rota have a listing of 15x8 ET5 (+5 offset) but only in 4x100 PCD so for our 4x114.3 again a special order of ten sets (40 rims). The guys I talked to here in NZ are either 240z with non coilovers or running coilovers on 240z or 260z suspension so a ET10 will work - an ET10 will hit the lower front spring perch on 260z struts (this is true with 15 and that is all I am concerned with as that is all that we can prove was used in period on race cars)

FYI these new RKR have a lot of brake clearances and a very flat in side shape so the 12.19" wilwood setup I have clears fine which is not the case with some 15" rims.

Pic will follow tomorrow I will edit/update this post.

And some more

Can you get 225 semi's in 15" in anything else besides yoki's? I thought the widest bridgestone did was 205/15

you asking about the rear rubber on my zed? If so they very old dunlop d1's 225/50/15 but toyo do the r888 in 225 and 235 50/15 well here in NZ they do.

[Gareth. J.]

Ah ok, was a guessing either bridgey or dunlop. Wheels look very good, whats your opinion on the finish quality?

very impressed rating is much higher than the older RB-R 690kg vs 390kg if I recall. If we can get in ET10 then running the 235/50/15 toyo's and all should fit in the body work

I dont get why you are so set on +10s?

16x8 +4 have plenty of space in the front and yes you have to spend $100 rolling the rear guards but its not that bigger deal.
The extra 4mm you get with a 0 offset isnt going to ruin anything and will give people with stock suspension a touch more clearance which would come in handy on a 260Z with the high purches on the rear.

Race cars - we want to run the larger 235/50/15 toyo which has a 245 foot print so almost 10" of rubber so having the rim a little more in board is required without flares...so that is why. If we are talking a road car that will not see the same suspension loads setup like we want to run sure the 0 is fine with a rolled lip on the rear - fronts are not a issue it is the rears at 0 offset that are too close with the camber we want to run. You can get the 0 to fit by running more neg camber on the rear but having too much on race car = less rubber on the track, we need rubber on the track for max grip levels. So that is why

[d3c0y]

I reckon with +4s i could fit a 235 under there it's only 5mm more to the outside. I can measure tonight if you want?
My car definitely sees high suspension loading the tyre has been touching the inside of the fender at the top!

What spring rates are you running? +4 will work but if custom ordered why not got +10 and get a little more fender clearances?

[d3c0y]

Couldnt you just get a bit machined off the hub face of the wheel? and then you could make a 0 offset a +10 or whatever you wanted? I bet that's all they do for the "custom" wheels.

I'm just running low king springs at the moment but will be going to 400# HKS coilovers shortly.

My point is you can probably fit the ET 0 so no custom ordering or machining

[NZeder]

yes but not the point...the car has 15x8 ET0 already geninue minilites and the rear is running too much negative camber to keep the setup way from the rolled lip already. You can't machine 10mm off the back or the wheel nuts will pass right through the rim.

So yes ET0 do work but not the ideal for the 235/50/15 will be too tight and that is the point. Well we run higher spring rates than that

Mike, With 235's hows the clearances on the front valance below the guard and to the chassis rail when steering is on full lock? Is that why you use a 50 profile...

Can't say car only has 225/50/15 on at the moment and if a race car is at full lock - things have gone sooooo wrong who cares if the tyres is rubbing the chassis rail. Front valance = cut, you might have already done that if you want to get a good amount of caster anyway. Again not a road car so not concerned about.

I guess the other option is run 15x8 ET0 and pull the wheels in a bit - ie negative camber on the rear by moving strut tops inwards then make sure the rose joints on the lower rear control arms can adjusts out most of the camber induced via the top movement = shorter Rear LCA. Then to keep the tracks close run some custom hubs up front that move the mounting face inwards by 5-10mm to match the back - will be running wider rubber so that puts things back in place where the 225/50/15 sit. The 235/50/15 are a total of 15mm wider than the R888 225/50/15
