Hi,

Whats the best car and tune for brands hatch indy circuit. rules are no more than 330bhp and 500pp and not lighter than 1250kg.

Cars have to be in the style of a British Touring Car Championship.

Thanks in advance.

Regards,

Al

If you look at the OP ( 1st post ) of the BTCCC thread @DaBomm4 linked, the cars used in that event would be good enough, this is what I built for the Round 1 winner and fastest lap at 49s ( Sports Soft 305HP, 1300kg ). The car has some limitation that can be removed, you can push the ballast rear ward for more rotation, lesser weight and more power. On Racing Hard, it should have no issue to get lower than 48s at Brands Hatch Indy ( same track on Rd 1 of BTCC )

Quoted Notes from the original replica post :





The power figure on the tune is 305HP / 305BHP, apparently the value of Asian GT6 HP ( mine ) is the same as EU GT6 BHP ( lewis ) :D The 1st gear ratio uses Xtrac 516 Catalogue as the real life Xtrac 516 1st gear ratio BTCC Build Spec 2.923 is not reachable. This is the setup that will be used on race day :) Car Number : 44


Here are the video of the races, so you can get an idea how quick the Civic that was used to win all the races :)

The Civic was tuned with tire wear in mind, and during those races, the tires ( SS ) - mainly the front that has the most loads, were in good condition by the end of each races ( 15 Laps ). This is a tire wear friendly tune, easier to drive and quite competitive ( won all 3 races of Rd 1 at Brands Indy - fastest laps on all 3 - with the lowest on race 3 - 49.387s ). Hope you find it helpful and good luck, God Speed !!
