Traction like a GTR from a GTST

[Robo's]

Well finally i bit the bullet and bought some Toyo Proxies RA1. These are a race tyre but are street legal similiar to the Bridgestone RE55. Im not expecting a very long life out of them but when you spend a fair bit of time spinning wheels, these are a huge releif. With the old Sumitunos HRZ 11's 255/40/17, 2nd gear wheel spin was at will as soon as boost hit. Good for showing off but not good for winning races. Now with these RA1's, i have 1st gear traction on the street and it is a rocket, no more hiding at traffic lights. Just for the record, i know RWD cars doing 1.6 60's with these tyres. Im not expecting 1.6, but if i can get 1.7/1.8 60's look out for a very low 12 and then i can drive it home. Perfecto.

how much are they?

[Robo's]

Their expensive at around $400 a pop but you spend all this money on the car to get it going fast, now you can put it to the ground.

[scathing]

They're not really drag tyres, so you might get better straight line traction with a different brand. They should be really good at cornering, though.

You considered Nittos?

[Cubes]

The drag spec Nitto's is what you want for straight line.

They handle quite well also.

Whatsisname had them on his car when it was making some where from 260-290rwkw and ran a low 12 with his granny shifting.

I remember him telling me he can get almost all the power from first down and second also.

Where do you buy Nittos from? and how much are they roughly?

[scathing]

Tempe Tyres stocks Nittos, I believe.

[Robo's]

These RA1's are also excelent in the wet. Dry weather traction is awesome. Bring on some traffic lights.

I just found this on Toyo's website:

The Proxes RA1 has the same construction & tread compound as the Nitto NT555R Extreme Drag Radial, and therefore provides very similar performance.

Don't know if I believe it but interesting... anyone know the price diff?

[JH32]

Toyo make Nitto as well don't they? So probably would be correct

[scathing]

If Toyo's RA1 (which they advertise as a clubsport circuit racing tyre) has the same construction and tread compound as Nitto's NT555R (which is reknown as a drag tyre), then one of them is going to suck at their advertised function.

Drag tyres make shit circuit tyres, because of their weak sidewalls. And vice versa.

With the rubber compound and tread pattern, I don't doubt that the circuit tyre will provide good grip compared to your regular street tyre off the line, but its still not ideal.

Refer to my original post, I know guys using these tyres at the drags and producing awesome launches. As for me, my car now bites hard.

If they cant do both (drag and cornering) why do alot of quick street cars use RE55's and also Ben from RacePace uses these on his track GTR.

The Toyo's are a great "cold start" tyre. On the track they are awesome for the first 2-3 laps. From that point on they go off like "Mums pants on Father's Day". Excellent hill climb tyre and for street -the only thing to look out for would be to make sure they are not overworked too much. A lot of high speed continuous cornering would see them go off. Once they do, they become very "squidgy".

Good tyre though - except they will probably wear fairly quickly.

So far i have noticed, i can still get wheelspin in 2nd when they are cold, but once they warm up, grip is phenominal. Im yet to try them down the 1/4 as yet but im predicting a nice drop in my times. I dont track race so i can't adivse you, but i only have them on the back so i would be understeering quite badly.

[Flaps]

Robo, what spec are these RA1's you have?

i.e you old Sumitunos HRZ 11's 255/40/17,

So which tyres are good for track days?

[Duncan]

Dunlop DZ02G or Bridgestone Re55

Hey. Dunc, are you using Yokohama A032R's or A048R's?

cheers

[Duncan]

Those bloody A032Rs....did you guys run the 48s? I am interested to see if they will be any better....I am hoping Gordon will be out of stock of the 32s when I need to buy the next set

Pete and Terry were having a tricky time with the 48s apparently?

[SLY33]

im running re55s's, awesome when warmed up, but im still shy at the traffic lights if ive been cruising around and they arent warmed up! Especially with this cold weather recently in SA, the damn things cool off too quick!
