yoko ad08's . oh my god, it now grips!
Discussion
When i got the tuscan a few weeks back it came with a set of goodyear eagle f1 gsd3's.
Great i thought, looked like they had plenty of tread so would save me buying new tyres for a while. I was wrong though as on closer inspection i saw the rear were left with about 2mm in the centres and after taking them off noticed that they were splitting up and also dipped in the centres which told me that the rubber had gone off and they had been overinflated for a period of time.
The car was lethal, i mean lethal. 1st gear, 2nd gear span all the way through, you hit a bump and the wheels would spin in most gear, which isnt funny at 80mph. i daren't push the thing basically.
So then i had a rebuild and had to run it in. I am now 100 miles away from the running in service but dom said from 500 miles i could take it up to 4500 rpm.
Even at this rpm the wheels could still spin up, take a roundabout a bit sharp and you would 100% be fighting for traction.
Theres a lovely corner near me. Its uphill, it goes to the left, then to the right and then to the left again.Very short and a real challenge to any car as theres so much weight transfer,its a second gear corner and in some cars it can almost be taken flat. Lets just say had i not have been limited to 4500 rpm i would have ended up in a field
So i started looking for tyres, i had run r888's before on an evo9 and putting them on made as much difference to the car as putting new suspension on! i kid you not!
I would have got 888's but rwd, nearly 400bhp is probably not wise on an excessivly soft tyre, i dont mind 5k per set but i just know they would be lasting maybe 2.5 if your lucky.
So i decided on the new ad08 which is basically a trackday tyre but not as aggresive or soft as the 888, you also get a full 8mm tread. They were meant to be quick to warm up too and better than 888's in the wet which means nothing to me as i drive like an elderly lady when it rains anyway. I would imagine though they will be better than any normal performance tyre in the dry.
My god what a difference they have made. 4500 rpm now makes the car feel slow, no wheelspin, no sideways unless you really throw it in, turn in is now kart like, the stiff sidewalls really compliment the stiff tuscan chassis. Hitting bumps is no longer a lottery as to weather im about to have a fight with the road.
You know when you drive a kart and you go round a hairpin and it hurts your ribs where its pressing you in the seat? well thats what it now almost feels like! As the car is still relativly new to me i dont 100% trust the back end, i do know that front wheel grip is unreal.
Obviously im still running in and know from my 3 days of driving at proper rpm before the engine went that the real power only really starts at 4500 rpm.
I think the wheels will still spin, but not uncontrolably like before and much more predictibly )i hope at least). Dry grip is going to be unreal!
Bear in mind i have done only maybe 100 miles on these tyres so after 500 they should be even better, I did find though with the 888's that they didnt really need scrubbing in though and were great from day one.
People say tuscans handle badly and are unpredictable.Yes i think if you were to leave the car as is, stick any old tyres and any old geometry on then yes they are! But i knew within the first mile of driving a tuscan they could be made to handle well.
So far i have had geometry done, proper tyres, gaz gold pros, spacers.
I am now left with raising the rack which will be done next week, and then having the geometry re done, im going to have it a bit more aggresive than it is now though i think, i have also just fitted the s splitter so hopefully once run in i should have awesome handling. Its never going to drive down a b road at the same speed as an evo or scooby but it will do it with much more passion i know that!

Good to hear you're getting it all sorted out. When I think back to how mine drove originally with the soft springs/rock hard shocks/static toe out moving to toe in on bump/stretched front tyres it's a shame to think that some owners only experienced the cars like this. It's such a different animal to drive with a few simple ish changes.
I went for 225/40/18 and 245/40/18 rear mainly because those will give the same rolling radius as the original tyre, i know from the mytuscan website that the s and later cars came with a larger tyre but in all honesty is 10mm front and 10mm rear really going to make a difference. Especially when i measure the ad08 in the above sizes and they are slightly wider than the goodyear eagle 235 (225 ado8 here) and nearly 20mm wider than the 225 bridgestone on my van! Yes 20mm!
The rack is being done at taylor tvr, he says about 1 hrs work plus the spacers so i would hope its well under £100 plus there will be a bit of cost for geometry being re done.
Compared to my old evo this car is awesome, don't get me wrong the evo was very quick with 410bhp, proper clutch, launch control and lots of goodies but it was almost boring, it was a gt so it had no ayc like the english ones and came with a rs box and diff which i believe is a normal lsd, believe it or not i never felt safe in it either.
The problem with evo's is that to get them sideways you need to be going very fast or really pushing it (at least mine with 888's was anyway). For that reason i never really found what it was like at the limit or what it would behave like. I always drive a car as if its going to oversteer and the evo just never ever did. I like to know the limit and in a tuscan you can find what it will do very easily

Thanks for the info, it all sounds fairly straightforward, are there any threads about that talk about how much if a difference it makes?m3jappa said:

Can understand your point of view here, I have a friend with a skyline pushing around 500bhp, and it is extremely fast, really is a giant killer. But, i wouldnt swap the Tuscan for it, not enough 'fun'!! Its just a bit too clinical for my liking.
