Had some of these fitted today to my TD's today
DZ03Gs I was after the previous version the DZ02G but was unable to get them, so i had to pay a bit more for latest incarnation.
All i can say is wow! and i have hardly tested them yet.
Cant get the car to spin up in third at all, just grip grip grip. Can get a bit of spin if i drop it in second above 5000 revs.
Tried a couple of launches and it only spun up top end of first, no spin at 2800rev launch
But the biggest benefit by far was on the exiting bends, no spin at all and could get the power down miles further back in the turn.
Cant wait to test them properly, but initial testing shows masses more grip than normal road tyres. Obviously this was going to happen, as thats what there for, but i was taken aback by the extra traction gained.
