Check the build dates mate.

Indeed, there are still some v710 new I think, but most are now v70a.

they are among the quicker tyres, especially on a lighter car. they were very popular when they were the IPRA control tyre about 10 years ago before they moved to the super expensive yokos. they performed better when buffed but I guess you don't want to bother.

one thing I found with v70A which may also be true in v710, high tyre pressures gave the best performance under the gtr. when I say high, I mean 42-44 hot which is outrageous

take them if the price is right

[boxheadmr]

Duncan, i think you have them mixed up as the V710's are the newer ones i thought

[evil_weevil]

yeah v710's are newish on the market.

I think Mark in the S13 has had good reports with them?

[Duncan]

ahh yep sorry, I was thinking of v700.

v710 looks pretty aggressive

BTW it probably doesn't matter for you, but v710 are not on the CAMS tyre list.

[Victory]

Clinton has a set of these for the Mazda and they make it handle so much better than an old car like that is entitled to. The biggest issue he had was finding the right tyre pressure to match the light weight of the car as they seem to be pressure sensitive.

[SRS13]

Both V710 and V70A are current tyres from memory.

I have not run these but Mark has run these on the S13 with very good success. They do like higher temps compared to most semis, 36-38psi (although these are not generally considered a semi, not a cams approved semi anyway). Mark estimated an improvement of 1.5-2 sec's a lap at EC and probably half that at Wakefield as compared to a similar sized V70A. Better braking, traction and cornering - which is expected when you look at the tread pattern. Longevity was also very good as he campaigned a set for almost 7 rounds! Other competitors say they are equivalent to an A050 medium or soft compound. For the price I don't think you can go wrong.

[boxheadmr]

price has a lot to do with it as the AO50's or Hankooks are 2000 to 2500 vs these which are 1100. I tried to run these in the SAU Nats without much luck and you will have to run as a slick tyre in supersprints.

Different subject with CASM but i think they need to look at the rules as there is a smaller difference between a semi slick and slick tyre now.

[evil_weevil]

with AASA - superTT and MX5 classes its run what you brought, Im up against blokes on slicks and semi's so yeah, these would be good!

for 219 a corner I think i'll give them a shot, although wont be running them till July at the earliest.

If I can go half a second quicker (vs r888) at wakie i'll be happy, that'll take me well into the mid to high 1.12's (shut up you sub 1.10 people! i have 75rwkw!) and would actually be competitive in superTT in a 10 lapper

[nismoman]

V710's are awesome. Best bang for buck and at just over $1000 even better value.

DO IT!

You won't regret it. I actually got 9 supersprint events out of 1 set. Only on the 9th event did the lap times drop off.

They still have life in them, just not as fast anymore.

On your light MX5 they will transform the car and you may get more life out of them.

Also against full slicks, they heat up quicker and you go faster sooner. Good for 5 laps but they can over heat if punished for longer.

Just remember they are designed as a autocross/sprint tyre.

[boxheadmr]

you saying the slicks are only good for 5 laps or the V710's?

[R31Nismoid]

A mate uses them on his S14 track car, 300-350rwkw or so - said they take a little more pressure hot than the O50 to perform well, reckons they are as good if not faster than the O50.

Then factor in the money side of it & they are good value when you considering the price of the others is almost double in some cases. You'd certainly think you could get .5 of a sec off going to them from R888s

Down here it's hit & miss if they will let you out with them in the wet, no idea what it'll be like for you guys up there as it seems to vary a bit between states/organisers. Be fairly certain if it was wet and at a CAMS event, no chance haha.

Brother has been using the v70A on the PRB Clubman for quite a few years now and very happy with them setting some great records 1:38 at the creek and 1:02 at Wakfeild. Winter time at Wakfeild Park a lighter car eg: clubmans and Lotus Elise can run the soft compounds if the budget can afford to have a spare set.

Jason Wright used the V710's on his WRX at one stage and dont think he went quicker that the V70A i would look at them for a MX5

[nismoman]

you saying the slicks are only good for 5 laps or the V710's?

I was talking about the V710's being good for 5 laps. Very consistent over 5 laps. 1st lap is just as fast as the 5th lap.

[evil_weevil]

hmm..race formats are 6 laps 1st race, 8 laps race 2 and race is a ten lapper.

food for thought! thanks lads!

and yes, a wet track is something id have to consider as I dont have spare rims to have other semi slicks on. doh

[nismoman]

On the MX5 I reckon you would be able to do 10 quick laps with the V710's.

I was worried about running the V710 on a wet track also, but luckily last year I didn't get a wet event all year.

You could alway bolt on a set of street tyres if it rains.

[Dale FZ1]

Any word from people running V710 on Skylines?

[zebra]

As above

And are they road legal? Ie do they have "not for highway use" etc on them

And how do they compare to the hoosier h6?

[hrd-hr30]

they're not road legal, just like all the other 2 groove "cheater slicks" from Hoosier and Hankook.

I bought my Kumho slicks when they were on special on FSport. They were a few years old. I suspect all their specials are older stock they want to move.

My "cheap" set of slicks cost me a front gaurd, front bar and a wheel repair and only completed 2 sprint before the blowouts started. They turned out to be the most expensive set of tyres I'd ever owned.

I had 2 blowouts and a delamination and have seen the exact same thing happen to others using Kumho semis and slicks. It doesn't happen to everyone who uses them, but I don't recommend Kumhos to anyone. Well, apart from the KU36 which copped a heap of abuse from my heavyweight Supra, but I wouldn't touch their semis or slicks ever again. Spend a bit more and get something that doesn't have the blowout question mark hanging over its head. Its not alot of fun when a tyre blows out as you turn in to a corner fully committed to it!
