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.... ???

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
