Driving on track for 500 spirited miles
have heard great things and can confirm these are superb....they stick to the road like baby poo to a blanket. and for the money they are unmatched.

went from a road based Pirelli tyre (rosso) to these and the step up in grip is very noticeable in the dry. I would say another 40% and they last longer when hot on track too.

sidewalls are much stiffer but that is good for fast road and track work. little harder on the road as you have less flex to absorb the bumps. but well worth the slight change there.

they even work in the wet and far better than the toyo 888 or pilot cup sport (which are lethal in the wet). the directional tread pattern helps out with water dispersal.

keep a look out on Tyreleader, Camskill or Mytyres for the best deals.

I got into a set for a 911 GT3 for just over £450 delivered. they only got to 285 wide on the rear but being a track tyre they are squarer so about the same as a road going 295 which is ideal.

running a 235 on the front and the turn in is so much sharper. has got rid of that turn in understeer you get on a 911, you can lean on the tyre and get on the power that bit earlier so its much smoother all round.

ignore the tyre brand snobbery and buy these. I can get 2 sets for the price of 1 Michelin or Pirelli. I will always chew threw 2 sets of rears for every 1 set of fronts so this is even better.

they seem to last fairly well too even after a full on track day at Bedford and have shown not much sign of wear! cracking tyre all round.

After replacing some R888s with these I can't say I've noticed much of a difference. Both are extremely good tyres, the V70a works great in dry and damp conditions but has some problems with standing water as they all do. I'm using the hard compound on the GT3 and they don't seem to go off as quickly as the R888s did.

Driving on track for 800 spirited miles
My comments only relate to track days as I rarely use the car on the road, except driving to and from the track.

My background is Porsche racing and so I drive my standard road Porsche accordingly on track days.

Fantastic dry grip and handling. Tyres are progressive on the limit and don't suddenly loose grip. Even in the wet they are progressive at the limit.

The rear tyres are at the end of their life after about 3-4 track days, depending upon the track. I have had the sidewalls disintegrate and the tread lift, typically on the 4th track day, on 3 separate occasions. So now I throw them away after 3 track days: following a blow out at 250km/hr. So why do I continue to use them? Because they have the best dry grip and handling in the dry when compared to any other road legal tyre on the market.

Nb: The front tyres last about 50% longer than the rear tyres and don't give problems.
