Thinking about grabbing a set of Toyo R888R over the cup2s this time around, the cup2s have been good but the bounce really makes me lose confidence in the car at times... plus reading all the reviews the 888r seems to be the one for track day tyres and that's mainly what I want it for.

Just wondering if anyone's used these did they fit ok on stock wheels, have you had any problems and feedback etc?
I had a few problems trying to find a garage that would fit the 265/305 cup2s to stock rims as mostly they would say they only fit stock sizes (probably for safety reasons, quite a lot also refuse to fit your own tyres as well)

315/30 rears seem quite big.. same for 285/35 fronts (basically putting the OEM rear sizes on the front :nervous:).. just wanted to check these are ok before i waste £800

Thanks :bowdown1:

ye i get that they might not be the best in the wet but I just want to try something different other than the cup2s.

I am tempted by the PS4s but feel like they are more of a road tyre than track day tyre




out of interest has anyone actually purchased the toyos from the GTROC shop??

They will fit perfectly, I run them on my dc2 on track once a month and they are pretty good in moist conditions with some heat in them as well.
Steer clear of standing water lol and you can easily kill a set in a day when Pushed hard

This was the day before a Coombe track session

This was the day after


It was open pit and we didn't get out much but they still wore quite well

They'll go straight on but they tramline very badly, crap in the wet and cold weather and extremely noisy. Once warmed up then they are very good on grip for track and drag racing or illegal street racing but for day to day use not good. MPSS's are better than both cup 2 's and 888's for all round use

They are actually crap for drag racing as the sidewalls are way too hard. I dont think they are that noisey and the new pattern is quieter than the old, in the damp with heat in them they are fine but as said avoid standing water.

With R888R I noticed a significant increase in trans temp due to the difference in rolling radius front to rear. The Cup2s ran significantly cooler and smoother.

I've got a set on standard rims and they're fine. I bought mine through the GTROC Shop last year but you may want to speak to nurburgringgtr directly now ...

How do you equate the increase in trans temp to the tyres?

They are designed to run on standard rims and I use them all the year round. Slight difficulty getting to the Autosport Show with new R888R fitted and driving through slushy snow!.

The reason for the increase in transmission temperatures is because the rears expand more when over 50c than the fronts and the rolling circumferences start being different front to rear by up t0 3% in extreme cases. This then causes the diffs to heat up and the centre clutch starts coming under pressure. Toyo are aware of this as it only really applies to MY14 cars onwards where the tolerances are less. Toyo are now producing the tyres that will eliminate this issue and will be available through the GTROC shop in a week or so.

Sounds good. How will it be possible to identify the new design? Is there a different marking or code?

Nothing will change on the tyre markings apart from the date of manufacture. Stocks are coming in as we speak.
