Bluesrule mentioned it a good 2 yr ago use the 595's and there good even better again are the rsr I'm sure the pro lads would have a lot more opinions on it but for me they do fine it's all about your suspension set up and tyre pressures, them factors make a massive difference it's hard for street as they cool and heat up with driving but no complaints so far and I'm on a limited budget.
Would be good to see what people are using and what pressures.

I think using non grip tyres on the front is limited to the people who know how their car will react when they position it a certain way and for a driver who has little experience it would just be disaster as in no control and make them panic.

As for Backwards entry's, ye need massive amount of speed to be anyway decent and at that your exit speed is seriously hard to maintain with 300ish bhp but sure it looks cool and I might have bent a subframe trying them on rsr's but running shit tyres for the sake of it i wouldn't bother.
