biggest semis other than the bridgestones are 295/30-18 (hankook vetnis Z221 and A050's), that diameter is about 80mm less than the standard wheel size on my car.

I wish there were some bigger smei slick options so we could match it with the EVO's

Kumho list 305/30ZR18 & 335/30ZR18 V70A semi slicks. Kumhos normally come in soft medium or hard compound too. Hornibrook motorsport is the QLD distributor

gotta say I had overlooked the kumho. how do they perform?

would a suboptimal sized A050 perform better than a better sized Khumo?

might need to experiment more. so many tyres so little time.

They're a good tyre, not great imo.

They're a few years behind the tech of Dunlop and Yoki.

Having said that, I have only used them in smaller sizes of 235 and 265.

We were fortunate to back to back the V70A's against the Dunlop O3G's at Mt Buller once, the Dunlops were nearly exactly a second a klm faster.

In the rain though, I think the Kuhmo is wonderful, I just think they struggle a little on heavy cars.

As I allude to though, they could have completely different behaviour in the enormous sizes.

Same as the Toyo's.

I still find it hard to believe 4 years on from the R35 being on the market that there are still no 19 or 20" R comps made (espec given porka's, lambo's, fez etc all run bigger wheels too).

yeah agree with the other guys about the cum-ho's being the same as toyo in that they work really well on lighter cars without the massive power but on the big brutes like GTRs with 1400+kg and 400kw+ they suffer. they might be great on the lotus but those things weigh bugger all like 800kg or so from memory? and have maybe 300kw?

the only real way to find out is try a set and see. it's an expensive lesson but given the effort in your build probably one worth learning for yourself.

I remember driving the 35 on track at OP and being shocked how much slower it was on R888s compared to the factory tyres (either the dunlops or bridgestonss). it was much more oversteery, and much slower over all and had much more roll courtesy of the sidewalls not coping with the weight.

Same as the Toyo's.

yeah it would be nice to have readily available 03Gs or RE55s or A050s in 20 inch sizes for R35s and lambos etc. plenty of guys getting serious with these cars that are being knobled by tyre availability.

Tire rack doesn't list A050's?! Only A048's :(

Edit - Or O3G's......

Anyone shed any light on that?

Edit - I've emailed them a request for info on those.

I rang them and couldnt get any sense out of them regards the o3g's Ben. I hope you have more luck.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
