511 Big Bores
 

So then who's running the new trf big bores on there 511's & what's the verdict?
I'm fancying some but only if there an improvement, I'm also running the upgrade kit, which on carpet seems to have made the car really aggressive?

I think the big bores are much nicer, I did some back to backs at RHR on 2wd yesterday expecting them to be not quite so good on the ripply stuff but felt better actually.

Cheers James, where did you get yours from? Stella?

I Have a set on my 502, have raced on bumpy astro track and the car was more stable plus direction changes seems to be quicker. Did not notice a big differance over jumps apart from a lot less pitchy.
