What am I best to do
 

Right guys I've got abit of a dilemma here, track day tomorrow and tyres are becoming a problem I was planning on running my 17" standard sti rims with the re070 but 2 of them the inner edge is down to the core, now the problem I have is I can either buy 2 part worn tyres to replace them or run my R888 but they only have 3mm i think a whole day on track would muller them!

Would I cause any damage running mis match tyres for a day, in sure after a few laps I can scrub them to the same depth in no time!

What's my best option, I would buy 4 but no1 local has 4 the same brand new, being at work today doesn't help so I can only pop out for about 45 mins max :( I should have checked my track wheels earlier and given myself more time but they were at the other house and I only collected them last night

Many thanks Dan

I have found a place that has 4 but they're jinyu budget c**p are they going to make me lose all the high speed Corning ability, but with the 4wd will it make much difference?
