The Jag is a blast on the track, but man it gets expensive. The others have much cheaper and readily available parts. If I wanted a more serious track car I'd go with a used high mileage normally aspirated Vette, strip the interior, race prep the suspension brakes,(unless it has CC) and add some bits for safety. Then dial it in until the engine needs a refresh, you'll literally destroy street cars by seconds a lap.

It's amazing the difference in speed between race prepped street cars and even the fastest factory car. Keep in mind I've leaving out the track built exotics, I've seen 458 challenge cars GT3RSs show up and mop up the track and set consistent laps for 30 minutes.

I could keep up in the straights if I got a perfect corner exit, but that extra weight really gets you after a lap of trying to keep up with them. Even wtih big brakes, coil overs and over 600HP , two tons is a lot of car.

If Jag came out with an F-Type SVR-GT in the vein of the Porsche GT/GT3-RS we would be more competitive. Jag needs to get back into GT racing so that technology filters down to the street cars. SVO has some brilliant engineers and I would love to see them get track focused, but you have to first go racing.
