    For what it's worth, I know the Americans love the RE71r, apparently they are streetable and pretty quiet for a semi.

    I'm curious to see how the Pilot Sport Cup 2 look after some track days, would appear i've fucked my PS4S, they are a good street tyre, but no track tyre that's for sure...

    Fixed. What's the suspension design and camber limit on the front of the Jag?

    Thanks for the pics. They don't look anywhere near as fucked as the PS4S on my car did after ~1hr of track time.

    My problem is finding a semi slick in the sizes I need

    255/35R20 and either 285/30R20 or 295/30R20

    I can't go to a smaller wheel because of the fucking huge brakes on the car, 18" or 19" is not an option.

    Can get the Pilot Sport Cup 2 in the 295/30R20, but not the 255/35R20. I could possibly go the 265/35R20 on the front, which is available, but i'm not 100% sold on the idea...

    And i'm looking at $2100 a set for the Cup 2 in these sizes, which is a bit fucken ouch...

    Rather than choke up this thread with the camber/alignment shit, i'll post that up in the Street Cars thread.

    Cheers

    Hold the fucking phones!

    https://www.hoosiertire.com/news/art...9D_Wheels.html

    The long anticipated track tire for newer production vehicles arriving from the factory with 20” Diameter wheels has finally arrived. Hoosier Tire’s track proven and race ready DOT approved R7 now is offered in five (5) new tire widths to fit 20” wheels. Air pressures and Camber settings listed in our Tire Care Tips should be applied to these new tires sizes designed with similar construction and tread compounds as other R7 tire sizes.

    Fucking "DOT approved" LOL, jesus....

    I emailed the local Hoosier distributor (Max Dumesny) to see if they can supply them.
    They are on their site for AUD $661 each in 245/35R20 and AUD $704 each in 285/30R20

    Yeah, the tyre companies take the DOT approval for America pretty liberally. IIRC the DOT approval was just to make the tyre legal for some race classes over there.

    I don't doubt that you would be laughed and then bent over and pineapple dipped in chilli inserted in Australia trying to pull the but it's DOT approved shit with plod here.

    Yeah tbh going full retard with slicks is probably not an option, i'd have to buy a trailer, and a Range Rover to tow it, and so on...

    A street legal semi is a much more sensible option.

    And wow, with a bit more digging I find that Toyo makes the R888R in my sizes, just not for sale in Australia... not shown on the Toyo Australia website, but found on the international site.

    And available to order from tirerack...

    Yeah i was going to try Tempe & St George next week, also Gordon Levin in Penrith who are the Toyo Motorsport dealer.

    But... looking at the prices of the R888R and the Cup2 on Tire Rack, they are very similar, for the same sizes.

    The set of R888R at USD $1594 is AUD $2275, and then I would still have to import them, which will cost a bomb, probably $3k for a set of tyres in the end.

    But a set of the Cup2 on the Bob Jane website in 245 & 285 come in at under $1850...

    Are the R888R going to be that much better than Cup2's ?

    I can't imagine i'll get my hands on a set of R888R for under $2k...

    Cup 2 are a far better tyre in my opinion but will wear very quickly on circuit, especially if your camber/toe settings aren't spot on for track.

    Yeah I was going to say the cup2 would likely be a better tyre.

    Yup, get your alignment sorted if going Cup2. Max the front camber whether or not your MacPherson strut/Double Wishbone (at least symmetrical XKS-GT ?). The sticky compound is on the outside and a poor alignment with the soft sidewall will probably do similar things to how your PS4s end up.

    R888R might be more stable for the car. Less tread blocks, less movement, and less heat despite the weight of the car. Most likely the tread depth is much less as well. Cup2 should be a far better dual-purpose tyre.
