US 91AKI premium is roughly equivalent to UK 97RON.

Mine are PSS all round. Both fronts were replaced prior to me collecting the car as 1 tyre had side wall damage, so not going to change those for a while.. So I don’t actually know if the fronts were wearing on the inner edge too at the time. Currently the front which only have 4,5k on them, seem fine all over. Wonder if I should stick with PSS on the rears to keep all tyres the same or try PS4’s and have mixed tyres.

I have only been responsible for about 5K of those miles in the last 2 years or so that I have owned the car😁. So it does seems like it’s not a problem.

My GSF is on 26k on what seems like original tyres going by the date code and I have noticed the inner edges of both rear tyres have worn down much more than the rest of the tyre. Really hard to spot unless you get under the car or have the wheels off. Had an advisory on it last year on the MOT, but all seemed ok when I looked but I am going to have to change it soon now. Car drives fine and doesn’t pull or anything. I remember reading somewhere that a lot of Lexus models do this and this is the way it is set up at the factory. Anyone know if this is the case or am I going to need the alignment done? And if so, to factory specs or something different? Thanks

I hadn’t heard of Bullet Performance for the GSF. How do you find it when cruising? Come across a couple of videos and it does sound good.

I use the Noco Genius chargers, which are a little more modern than CTEK. I have a small 1amp charger to maintaining the the battery over the winter when the GSF does not get much use. It can be left permanently connected to the battery and will maintain it one full. The wiring system is need and the cable an be kept attacked to the battery even when the car is use as it come with a waterproof connected to hook up with the charger. Have 5amp version of the charger too.

No 99RON won’t cause excess wear or damage any car designed for 95RON. At worst you won’t experience any benefit . Most modern cars will adapt to 99RON not just performance cars, and advance the ignition point and be more fuel efficient. And now the lower enthenol content further improve the efficiency compared to 95RON

Yes I think it’s the colour too.

Says here you can add a valve to the QS exhaust. May be worth seeing if it’s still and option on fitted systems. https://quicksilverexhausts.store/blogs/news/112494663-valve-system-launched-for-lexus-rcf

Thanks, I don’t often look past the F Club subforum. Was going to renew my warranty later this year but seems I have saved a bundle as I am booked in for service next week. I wonder if this will firm up private sale used car values now.

Just spotted this https://www.autoexpress.co.uk/toyota/355133/toyota-launches-groundbreaking-10-year-warranty No need to have purchased the car from a main dealer or of have FLSH, by the sounds of it, to qualify. and it’s on the Toyota website but not yet on the Lexus site. https://mag.toyota.co.uk/toyota-warranty-how-it-works/

You may right, just had another look, the raised spokes are flat which may be reflecting more light than the curved lower ones.

UK cars were fitted with the hand polished ( rather than diamond cut) wheel option. The raised spokes are polished and the lower ones are painted.

This is the same colour seats in mine.
