Rear GT ducts is direct fit. For front just use motorsport back plates kit.

Man, will all that upgrades it is odd how your friend is faster in that 250hp skoda... i have a Seat Supercopa MK2 (Seat Sport racecar 2.0TFSI/DSG). Stock is 300hp but engine was deeply rebuilt and forged. Now has 450hp. So i know pretty well what a factory race car can do on track....

You really need run on slicks. There is 18" wheels that clear 380mm. Just buy some fresh michelin slick porsche cup.

@Tiago... i am sorry... the Skoda details were given as a fact what a stripped out race prepped car can do vis a vis the stock (but more powerful) car.. I did not mean that it was faster than a Porsche... sorry if i miscommunicated... but i have ordered the GT3 front brake ducts.. thank you for suggesting.. now i have to hone my racing skills.. ;) to push a lighter car more and enjoy in the process...

There is 18" wheels that clear 380mm - which make and model?

18" clear 380mm

Don't forget to buy also GT2/3 rear brake ducts also.

For the time being i have a set of the OEM Turbo wheels another set of the VOLK Rays 5 spoke. both are in stock sizes. The Rays are with the CUP 2's (for Track duty) and the Turbo wheels are with PS 4S (for daily use). Ordered the rear GT3 brake ducts too.. Thanks
