I'm considering the following combination on my T350C and wondered if anyone has gone the same route and how they found it.

Front SP12 8" x 18" + Sessantas 225/40x18
Rear SP12 9" x 18" + Sessantas 255/35x18

I've searched back various threads on the forum and based on this the combination ought to work reasonably well, but with a slight risk of rubbing on the front due to the increased tyre height (although I couldn't find anyone running the Vreds who had this problem).

The car has had geo and ride height set, with negative camber set to the most negative end of the range.

My Goodyear Eagle F1s have a 2004 date code! Time to get rid of them....

I've tried that tyre size and make on my T350C on stock spiders. The 40 profile front is unfortunately a suck it and see test as each car seems to be slightly different for clearance. It rubbed too much for my liking on mine at full lock. I also think the sessantas are a little too hard a compound tyre for the T350/Tamora and Goodyear Asymetrics seem grippier imo. YMMV.

Thanks, sounds like it's suck it and see on the fronts. Thanks for your comments on the Vredesteins. C

I use SP12 wheels for track use but have gone for the 17" versions as I was recommended these for track due to the better size tyres you can fit with R888 tyres only coming in limited sizes.

I have 8x17 front and 9x17 rear, intended to run with 235/40 17 front and 255/40 17 rear. I run Toyo R888s.

I've sp12 225/40 265/35 R1R

the front RHS caught on occasionally the rear of the light pod cover till it wore through. reglassed it from the inside and no more issues since. perhaps a little car to car variability.

the rears catch again occasionally, a small ride height increase stopped that, but they are 265

Do you happen to know the wheel offsets? I know they are different to the original PRO RACE 1.2 options but I saved this information very securely ... can't find it anywhere on my harddisk frown

Thanks

Are the sessantas that bad, was thinking about putting a full set on as the price seems good and heard a few people rave about them.

I wouldn't say Sessantas are bad , far gripper than The Hancooks they replaced but Goodyear Asyms seem to feel gripper with more precise turn in . . Ps I never liked the old Goodyear F1 tyres and felt they had very poor wet grip . Note I also think tyre opinions without test data are very subjective and one mans meat is another mans poison

Got the new SP12 rims on Friday and on balance also decided to go for the Vreds. 255/35/18 at back and 225/40/18 at front. No rubbing so far on trip to Goodwood yesterday. Albeit they are only just scrubbed in, the dry rear grip seems fine. I do notice the difference on the front with the 40 profile - slightly different steering - so far no problems but slightly less firm.

Just also got my TPMS set up working (have posted this on another thread).

Serg - what pressure are you running your Vreds at? I've started with 24 all round and note that when running they go up to 26-27 as the tyres warm up (great gadget the TPMS).

One set of very good condition spiders going on Ebay if anyone is interested.

I have them at 24psi. I noticed a big difference in comfort, it took the harsh edge off the hard r1 46mm nitrons that I have. The steering is slightly less direct, but the car isnt skipping around the rough roads anymore, and only goes where you point it. V happy.
