Cheers mate,

But how many kms will these semi slicks do?

At least 20,000 kms. Depends how you drive though.

The Star Specs are also a good alternative. Bit cheaper with similar performance. Check out Tire Racks in depth review for the max performance tires.

This depends on what you are going to use them for r comps on a daily drive are not going to last.
