Thanks Buster. Ill try him again next set of tyres, but last time i got a price off him for the 540s they were like $10 cheaper each then the Dunlops. So was quoted something like $420 each for 235/45/17 (may have been 235/40/17)

Decided to stick wih Dunlops as i have nothing but praise for the guys who sell them in Sydney.

  • 2 weeks later...

has anyone used 540's in 16inch? say 225/50 on a std rim? Im wondering if they will perform better than a 17 or 18inch street tyre in terms of ->do you get sidewall flex/rolling on hard cornering as you would with a 16inch street tyre?

Im tempted in fitting them to std rims for track, as the 16in tyres seem heaps cheaper.

cheers

I've not used either 540s or 16" track tyres, but I do use dunlop d01js in 17s....and one of the major improvements in R tyres is less sidewall flex due to much stiffer sidewalls.....so, 16s should still be great. The only real improvement from low profile tyres eg 17s, 18s, is due to stiffer sidewalls.

Sly, i was (and will do when i need new tyres) going to do this on the stockers, but apparently the stocky rim is only 6" wide. It is more ideally suited to a 205/55 16 and they're available in 540s. They should hold on as well as a 17" when warm.

I'm guessing that of you run reasonable pressure you won't get much roll.

205's eh? sounds a bit small but if they are cheap it would be ok! do you know what these can be had for ronin?

are std rims only 6 inch wide? i thought maybe 6 1/2... ive got 225/50 street tyres on stockies that look fine, do bridgestone make 225/50 16 540's?

cheers!

Yes they do make 225/50/16 as it is this size that my boss uses on his vn comodore race car.

I know you guys are talking about circuit racing but how would these tyres go for drag racing?

With 200rwkw in an r32 using 245/40/18s with about 50 % tread iam having big traction problems and cannot get my times down to where they should be.

My plan is for when i go to the creek in about a month to fit 2 540s (used ones from the race car) to my stock rims to go on the back using about 20 psi in them.

Will this improve my launches ect.... ???

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
