I am running evo front disks 320mm diam, uk front disks are
325mm so in theory im loosing 2.5mm from the radius from using evo disks over uk's
On the rears im using Jspec disks 307mm uk supra 322mm again im loosing 7.5mm from the radius
in my personal opinion this is not a great deal of loss to worry about the only gain I guess would be more heat dissipation through a bigger disk, but with a loss of 2.5mm and 7.5mm will this be noticeable?
The argument with regards to the weight differences between cars I do not have any specs on the weights of either cars.
With regards to performance, my car is running just shy of 600bhp I had the chance to put them to the test last sunday this will be the front conversion not with the rears on aswell, i managed speeds of upto 185mph over several laps with no problems at all some brake fade but this did not result in a total loss in braking and they were quick to recover. I had a few laps paired up with John (pig) running the same power with a full UK brake setup would be nice to see how they were compaired to mine.
Im not trying to promote these kits, im just trying to put my side up.
