    GR Yaris POWER STEERING FAILS mid turn on the Nürburgring

    My car was off the road for about 6 months during which time I had the Wiborg arms fitted, and I've only been out once since then, so I don't know if I can really give honest back-to-back feedback on how much difference they made. The car is fantastic to drive - super neutral, will 4-wheel drift...

    GR Yaris POWER STEERING FAILS mid turn on the Nürburgring

    I had the EPAS issues before getting the wiborg arms, and still have them with the arms fitted. Trailing the brakes makes it happen pretty reliably - I've kinda got used to it now, but would be keen to find a solution. My car is modified enough that taking it to Toyota to look it isn't really...

    GR Yaris Ideal tyre width for road use?

    Reducing unsprung weight makes a massive difference to how the car feels and rides, I have 18x9 wheels for track and they are noticeably worse than OEM for road feel and harshness. I would aim for the lightest wheel/tyre combo possible, and OEM forged wheels are lighter than 95% of aftermarket...

    GR Yaris Misha just gave us all a present!

    If your track driving is very similar to your fast road driving, you're doing at least one of them very wrong :D

    GR Yaris Light 18x9 rims on budget?

    ET45. Have you ordered wheel nuts with them? I can’t remember the details but they are an odd size, very small OD.

    GR Yaris Light 18x9 rims on budget?

    I bought 18x9 JR wheels, I can’t remember the exact details, but they were a bit heavier than the website claims.

    GR Yaris GR Yaris and oil pressure (in track use)

    I should have said, I already have the baffled sump, and sticky 255/35 a052 tyres. I was having issues, so I overfilled by half a litre, and it was fine for a few hours, then the syvecs tripped again later in the day, so I gave up and went home. I don’t know if I was getting faster during the...

    GR Yaris GR Yaris and oil pressure (in track use)

    I’ve been suffering from syvecs limp mode on track - is there any down side to overfilling oil? I have had mixed results with overfilling, am in the process of installing a catch can, and might try slightly thicker oil, but I’m close to the point of going for an accusump (as mentioned above)...

    GR Yaris Best torque arm mount to improve gear shift

    I was in a very similar position, I’ve had the whiteline insert for over a year, it helped but the shift was still never perfect, mostly noticed on track under very heavy braking. I just changed to verkline insert, there is much more vibration at low revs, but the shift feels noticeably better...

    GR Yaris Thoughts on aftermarket discs and calipers choice

    I think broadly speaking, yes, that would benefit your brake performance. The pad and disc can take much higher temperatures than the brake fluid (800 vs 300C), and the disc has loads of airflow so can get rid of the heat, nothing good comes from heating up the caliper (you can damage the seals)...

    GR Yaris Thoughts on aftermarket discs and calipers choice

    I believe the TDE discs are made by surface transforms - they’re not refurbished, they are a proper bit of kit. I haven’t swapped discs yet, but did have fade on track first time out, and used pretty much a full set of pads. I swapped fluid & pads and added hrnshn vents and HEL shims, and have...

    GR Yaris Best suspension/is it worth it ??

    They’re an incredible bit of kit - in the normal world, the ohlins r&t dampers are a high end damper, only in motorsport-world could they be considered a budget, entry-level offering! What are your plans with the car? Got any outings booked yet? What about other mods?
