Had a quick look for the 50s for you, but tweeks appear not to stock that model.
My tyres are little 14 185s for (cheaper for tight wad's)
They do stock cheaper R specs in larger sizes.

How did I not know about Demon Tweeks???? That site's a serious wallet buster!

Anyway, according to Toyo's weird naming standard, GG is "medium", mostly used for track work, while GGG is "soft", typically for hillclimbs and motorkhana. The GGs usually take me a lap or two to warm up and then they hold max grip for 5 or 6 laps. For longer sessions I'll run at 90% for a lap after 5 and then they're good for another 5 hard.

I bought 205x50x15 R888 GG (medium) from Talebs for $225 each. I also bought some cheap rims 15x6.5 which are a bit heavy but OK for track days. All up the tyres and rims with wheel nuts, fitted and balanced and delivered to my door in Canberra was $1,300.

I ordered them one afternoon and they were at my house (Sydney to Canberra) in less than 24 hours.

I would have preferred Kumho V70A mediums, but the best price I could get was around $350 delivered.

The R888 is a good compromise and I reduced ny hillclimb time by 1.5 seconds to 50.5 and WP lap by a similar amount to 1.15.08 - so happy with the R888 as value for money. Previously ran Kumho KU36.

So taleb don't have R888 in stock for a few weeks (in 205/50/15), but they suggested the Nitto NT01 as an alternative for cheaper ($200ea). Has anyone had any experience with the NT01?

Also Peter, just out of interest what was your difference in time between KU36 and R888?

Search the US board, the Nitto's get good feedback there.

I'm keen to have a go on the Nitto tyre at some point. I think they would have better staying power for race use as the tread blocks are so huge, they are not going to be moving around and there are less 'edges' to overheat.

R888 offer good value I think but chatting to people at the track everyone says that the best semi-slick out there is the Bridgestone RE55. Pricey but not far off a full slick in terms of grip and ability to withstand heat.

I'm going to start running Dunlop slicks on my car. They are about $400 each in 220/50/15.

If you're planning on doing club trackdays or State Supersprints, it's worth noting that Nitto tyres are not on the "Production Car Tyre List" and therefore are not eligible for use.

RE55s get two thumbs up from me. They're only slightly more expensive than Kumhos, last much longer and wear more evenly (V70As tend to wear heavily in the middle of the tread pattern).

Mitch

My times dropped approx 1.5 seconds from the KU36 to R888 with the car in similar trim. The R888s seem more affected by a cold day than the road spec KU36. The R888s also required a bit more aggresive camber than road spec tyres (I have - 2.2 on the front to get initial turn-in and may go for more).

I chose the R888s on the basis of price for reasonable performance and hopefully a reasonable life as they were not much more expensive than the KU36s or Federal performance road tyres. I also drive on them to the track. The Bridgestone RE55, Dunlop D03, Yokohama 50 or Kumho V70A would all be quicker if you wanted to spend a little more.

I ran the Kumho's V70A on Fanta and was very happy with them. I managed consistent 1.10s on V70As compared to a best of 1.09.25 on full Dunlop slicks.

I have not tried the Bridgestones, but Bryan's times on them show they work well.

Demon Tweeks pricing is great but make sure you factor in $300 AUS to ship 4 of them here. That's a quote from those folk directly.
