Some questions on roadtrip and tyre advice

[Shortfork]

Hi peeps can you advise  which tyres to get for my Elise series 3 ad 07s or ad 08r or ad 08rs car is mainly used for road with about four track days a year i have only known ad07s. Thanks next question roadtrip to Scotland Nc 500 anyone done this in a lotus and go how did you do for petrol stations for super unleaded, is the applescross route hairpins doable or do the car ground out many thanks

Make sure the AD07’s are the current version plus same with AD08r check date stamps and I’ve heard mixed reviews about the new rs tyre. To be honest though I’d bet anyone a tenner to tell the difference on road/odd track day between these three. If it was me and it had to be these three, I’d just be buying the newest date stamp and the best price of any of them.
