wheels of choice for a 32/33/34 gtr in targa with bigger brakes?

I have alcon's (365mm) and heard nightmares of finding wheels that fit over the caliper

obviously would have to be 10" wide or less to be legal. no idea what to do with my weds 10.5" rims.

We ran the 365 Alcon package under 34 wheels, you can see there was some issues with foreign object clearance (always is with big brakes and rallies) but they cheared fine.

Wheel is dependant on whether it is a 32, 33, or 34, as they obviously all had differing sizes from factory.

The supp regs clearly state for Early Modern;

Early Modern & All Classic: Wheel diameters may be varied by a maximum of plus or minus 2” and wheel width varied up to 2” from the standard dimensions. Classic vehicles may only increase sizes up to maximum of 18 x 9 inches.

So, R32= 18x10's

R33 = 19 x 10.5

R34 = 20 x 11 (full hectic)

marlin, R33 would be 19X11. as they had 17X9 stock.

it goes:

R32 16X8

R32 Vspec (some run as this I believe?) 17X8.5

R33 17X9

R34 18X9

so just add your 2X2 to those.

Yeah you're right Baron.... I knew that after I posted it, but you got the drift ;)

It used to be 1 + 1, We had to run 17 x 8 on my GTS-t, now we have 18 x 9 which makes me happier trying to catch the Evos (in the dry at least) :)

32 vspec was 17x8 - so 19x10 max not 10.5.

The +2" wheel width is one of the worst things about the current rules....everyone has to spend more on tyres because everyone does, and the crashes are harder.

Blaise reckons one of his biggest advantages was being able to run bigger rubber than the rest of the EMO's (he squeezed on 255 rubber onto his cars where as the others were all on 245's).

The funny thing is for me my tyre choice was the Yoki A050's and the biggest they have been making is 265's. I have a set of 10.5's and a set of 9.5's and I personally found that the A050's in 265's sat better on the 9.5's than they did on the 10.5's (where as the RE55's and DZ03's were both better on the 10.5's in a 265 tyre).

But as soon as the 295's were out I'd have been switching to them on the 10.5's as my preference.

^^^^ My gut feel on the rubber issue, was the bigger tyres gave me more rubber to wear down so hopefully longer tyre life. Made me more confidfent of getting to the end on the one set of mediums. Turned out tyre wear was definatly not an issue for me, but it is a light car with moderate linear power as opposed to the heavier GTR's and bigger HP.

But for outright pace, I did do back to back testing between 235's (what most emos run) and 255's on the same day and there was two tenths of stuff all in it. I went about 0.4sec a lap quicker at best, but also had gone from worn 235's to new 255's so not sure if most of the gain was just that I had fresher rubber. Wasnt a massive improvement, but at the same time cant be a bad thing. Most forms of motorsport if given the opportunity, tend to run the biggest rubber they can.

Greg Garwood is looking for a good tarmac prepped R32 GTR if anyone knows of one?

Yes, I've told him about Jurgenson's and I'm sure he'll follow that up. - edit - Drew doesn't wish to sell now.

    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
    • LOL, all of the CAI like Craig I just need to put a hole saw through my bumper Done and dusted, the car runs, which is nice, I'll take it for a spin when the weather clears up Just need to put the bumper back on for good
    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
