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.... ???

    • What's on the front of their building?
    • Jax Tyres Smithfeild Ive gone there a few time, well for tyres. on my 3rd visit I spoke to the dude and told how i just got slugged for rotors, brakes ect. His reply was golden; have you read whats on the front of the building. Never forgot it.       before picture, good friend got all these goodies installed.  Well time to study, servicing, maintenance all before this weekend driving lesson.  
    • Hello, first of, I’ve looked at many threads on this code but none have helped me, if you know one that will help me feel free to post a link.   Now to my problem. Recently I was driving and noticed the check engine light came on. I went home and did the test to see what code it gave. I got the 21 code but everything seems fine with the car, no misfire, idle is good, acceleration is the same as when I bought it. I mean no signs of obvious failure. If no misfire is happening I can rule out the coil packs right? Which is about 98% of posts saying it is. If anyone has had this happen and found the issues let me know please. No other lights are on.   The car WAS due for an oil change. I since then changed it so idk if that triggers code 21. Either way it hasn’t turned off.
    • Your both right, it may hold a bit longer then.  Soon I need to change the synchros, should I fit the billet plate while I'm at it? Or just a waste of money?
    • Some of the east coast US Stagea got together this past weekend at Lime Rock Park in CT for Grid Life Circuit Legends. This is probably my favorite pic of the shoot with @Morgan.Mundahl on IG. Hope we get more stags out next year! i think I spotted 5 other than my own at the event.
