    Last event of the year for me and back to Curborough:
  2. G1en
    I have noticed an improvement in acceleration/gearing going from a 40 profile to a 35 profile rear tyre this year. essentially like dropping a cog on a pushbike so its easier for the drivetrain to turn, thats prob why he says going from a 19-18 inch wheel reaps more benefit than a 10 to 9kg wheel swap. you can improve the gearing by either a final drive swap, smaller wheels or lower profile tyres, it all does the same thing in essense. I am no expert but I think thats what he is getting at without going into the detail of confusing the viewer. Its also probably why lots of sprint/hillclimb cars (that i have seen) fit the smallest but widest wheels they can get away with to clear the brakes/arches. No doubt a lighter wheel is better and we should always opt for that if competing (and strength taken in to consideration) but your not going to be adding 50kg of multiplied weight to the car and adding 5 seconds to your laptime by going a kilo per wheel heavier like the internet would have you believe.

    Yeah, it basically confirms what my thoughts were. The wheel weight makes a small difference but nowhere near the 4 times or 5 times unsprung weight multiplier banded about. he doesn't and no one seems to factor in that a lightweight wheel is 9kg say against a 12kg cast wheel but you also have 9kg of brake disc and 10kg of tyre plus rest of calipers and hubs so as a % overall weight reduction its negligible. basically lighter is better but not worth getting hung up about a few pounds/kilos as any non professional driver will not notice or care, buy the wheels you like.

    Penultimate event of the season:
  5. G1en
    At the start of the year I fitted new discs and pads ready for the season. I went for Black Diamond (i think) slotted discs and PBS Comp Pads. I noticed after a few events hairline fractures/cracks in the discs but just ignored them as they didn't seem to get any worse. Well during this weekend at Blyton, they had developed from just a hairline crack to more like the grand canyon. You can see all the hairline ones i mentioned but I think you will agree it might not be advisable to be slamming on the anchors from 110mph to 30mph on track with these. The other side - pic below - crack wend all way through the disc! So with a full weekend at Curborough this weekend coming I thought i better not risk them, Tarmac Sportz to the rescue who only had Pagid "standard" discs in stock but with only today to fit them I couldn't wait to order anything so a trip to Derby in the morning and then got them fitted this afternoon. Thanks Chris. And while I was at Tarmac HQ, I picked up my diff brace I had ordered and fitted that as well, with the abuse I give the car, its a bit of extra reassurance the diff wont part ways with the subframe anytime soon. Video of Blyton to follow below, safe to say, I need a gearbox rebuild asap

    Back to Harewood this weekend .

    Next Installment from Curborough Events thick and fast now
  14. G1en
    Its good fun, very fast and flowing but simple. I would imagine its very hard on tyres and brakes if you did lap after lap, especially the front and rear left at Gerrards *if pushing to the limits but definately worth going if you have the chance.
