Hey guys and gals,

I have just purchased a 2008 370GT SP through Geoff at Prestige Motorsport (who has so far been extremely helpful and actually found me a better car, on paper, than I thought I would get for the money) and it should be on its way very soon. Does anyone have any advice as to what tyres I should go for, to get it past compliance?

Tyre sizes are: Front: 225/45R19

Rear: 245/40R19

The car is going to be a daily driver so i dont want anything over the top or that gives a harsher ride and dont want to spend a fortune, up to $1500 for the set, maximum. Does anyone know of a good spot to get them in Brisbane? The car will be complied in Brisbane and I am in WA so I want to make sure that the compliance place doesnt try to make any extra $$$ on the tyres.

On a different topic, I have been looking at some of the basic mods that people recommend and have read about the grounding kit that suuposedly improves throttle response etc. Does anyone have any experience with these and know if they actually make any difference?

Attached is the Auction Sheet for the car, from Japan.

Cheers

Al

hey mate not sure with tire sizes and all but just thought I'd add my 2c, I had stock 17" on v35 coupe and tires where Yokohama advan sports and they were very very good they had minimal noise and enormous grip and barely changed in wet conditions

Mate, I too just got a G37. And the dealer recommended that I source my tyres from the US.

Apparently the price difference plus postage is still MUCH cheaper than what you can get down here.

+1 on the Advans. I'm running 255/20 front & 285/20 rear and the grip in all conditions is pretty hard to beat.

For a daily I would look at these:

Do tyres from the US meet the Australian Standards criteria? this could cause issues for compliance.....

It would be f'ed up if they dont accept the Jap tyres that are on it but let you put other imported tyres on......but then again.....thats government for you....

my car came with the factory jdm spec potenzas, so guess it depends on the compliancer?

no need to get tyres from the states fellas, buying tyres isn't a big problem if you know what you're looking for

wouldn't buy tyres unless I can see them first anyway, just find a tyre shop you trust

I have the 19" sport stockies & wanted to stay within factory spec,

so I run a 235/40/19 on the front which will still give an accurate speedo reading

running 245/40/19 on the rears

you can run a wider tyre on these wheels if you want, just google search a tyre size calculator so you stay within spec

===================================

about mods I have a grounding kit, lowered springs,exhaust & eibach pro swaybars

grounding kit actually made the auto feel smoother to shift (useless if you buy a manual as the difference felt is in the auto gearchange response), small but noticable improvement to response

lowered springs were for getting rid of large front wheel gap, Pain in the ass for getting around sydney but not too bad if you angle your entry

swaybars are the best investment I made, improved the handling 100%

exhaust was just for the sound, not much of a performance improvement as the base level performance is good anyway

shied away from getting intakes etc as my car is a daily driver & don't want to go crazy, besides supposed to be saving up for other things

Hey YoYo,

Where did you get your springs and sway bars from. I really really want.

I live in Sydney

Any help cheers :)

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer
