  1. Thanks for your thoughts. I've been running Kumhos in 215 fronts and 235 rears for years - heating the rears up has never been a problem which is why I was wondering if 245 ZZS might work. Sounds like they would probably rub on something though. I was worried about the wide fronts in a 1B although I know Mike Sankey runs them and is still breaking his PBs. 

    I think I will try 185 front and 215 rear then. Will the 185s fit on 7.5" rims though? Avon seem to recommend 7" max.

  2. As we are likely to compete in class 5 this year, we need to buy new tyres. It seems that Avon ZZS are the tyre of choice now and I guess most people are using 185/55R13 and 215/55R13. Has anyone used 215 on the front with 245/50R13 on the rear? I know the 215 fronts can be fitted but I'm not sure if 245s will fit on the rear. We currently run 235 Kumho on the rear and they are quite close to the ARB.

    I guess the other question is why ZZR are not preferred over ZZS. I know one competitor will be running ZZR but I understand most of the 2021 class 4 decided ZZS were better.

  3. Great work John.

    If anyone else has written or would be prepared to write a guide then please contact me. It can be as short or long a job as you like but if you think a fellow owner (especially a new one) could get some help from your experience then please give it a go. John has set the gold standard with step by step instructions, photographs and lists of parts and tools but any documented tips or instructions are useful.

  4. It's true - we will likely end up with class 5 just being this year's class 6 competitors with maybe one or two who are currently in 4 and over the 220bhp. For me, that would not be a good situation as part of the reason to move classes is to be with more competitors.

  5. Dual Drives:

     

    The driver who finished higher in the previous year’s championship will run first or in the previous batch wherever possible.

    This is to reduce  any possible advantage for the faster driver by running on warm tyres.

    The problem then is that the faster driver is then running out of class which could result in an advantage/disadvantage depending on weather changes so in direct conflict with the suggested rule for drivers competing in other championships. In the past we have agreed that the warm tyres benefit is minimal due to the normal gap between batches.

  6. We're using a Laminova oil/water heat exchanger on our 260bhp Raceline built Duratec which works well. It still takes a while for the oil to heat up since the Laminova is fitted in the coolant hose to the radiator but it does manage the oil temperature effectively once the coolant 'stat is open (82deg 'stat). Obviously you need a decent radiator and we are using a standard Radtec with no issues. We ensure that the oil temp is over 60degC before using full throttle/revs.

  7. I just checked on this excellent guide produced for the club by Avon tyres and ZZS are available in 195/50R15. These would meet your criteria I think (apart from the cost bit maybe). I normally wouldn't recommend a tyre I hadn't driven on but a lot of the club sprinters use these as do some of the racers but they still have a "proper tread" on them. 

    I use Kumho V70A in a medium compound for road/track use and supersoft compound for sprinting.They are a good tyre but the sidewalls are a bit stiff for some people's taste in road use. They do have a bit more tread than some of the semi slicks.

    If you find any tyre tramlining on the road then you could try a tiny bit of toe-in on the front. I prefer a fair bit of toe out these days as it's mostly used on track but in the past I ran Yokhama A048R and they tramlined quite a lot but a smidge of toe-in helped.

  8. Glad to hear that Debbie is fine and that you should get the car back on the road soon.

    Black duct tape will do the job - it's held my car together for years *rofl*

    Personally, I'd give it a go using fibreglass mat and resin on the inside of the wing/nosecone - that will at least hold them together. The important bit is to make sure the surface is really clean and well keyed to give the resin the best chance of bonding. Dave Gemzoe helped me with a rear wing that was basically destroyed and we got it to stay together until I hit another cone with it!

    Or you can start the path to downgraditus - the realisation that carbon is too expensive for a track car and fibreglass is the future *hehe*

  9. It looks like Justin has been appointed chief garage arranger *hehe*

    @Graham. In previous years the organisers have allocated 3 garages to the L7C and then one or two enterprising individuals have booked extra ones as needed - IIRC there is a charge for this but I couldn't swear to it. Perhaps you could check with Longton.

    We'll need 5 garages to cover the entries so far. EZ-ups are great but a garage is better *yes* especially considering the wide range of possible weather possible at Anglesey *biggrin*
