Hey Guys,

Can someone recommend me the optimum semi slick tyre size to use on my R32 GTR rims (16"x8") for track duties. I'm looking at buying a set of Toyo R888 245/45/16 but not sure if width and sidewall height is best suited for the track.

Thanks

Ive got 265 40/17 Dunlop D01J on 17 x 9, I think its a matter of finding a supplier for the size your after, good luck with your search.

if your track work is sprints, than I'd stick with 225/50. 245 on an 8" rim will be less responsive and be difficult to get pressures right to optimise the contact patch.

I'd also recommend selecting another brand of semi slick - I'm not at all impressed with R888s.

What other semis are you comparing them too.

Most people have found R888's to be the best grip vs life vs price semi available.

The performance of the Yoko's are better (they heat cycle out after about 15-20 runs ie 2-3 track days), the R888's whilst not quite as good performance wise last 5 plus times as long.

I won't buy the R888's again because I don't think they are as good but I can also confirm they last WAY longer than any other semi! Also they may be better for heavier cars.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
