You have 2 weak links in the drive train, but as long as you don't abuse it too much it should be fine with street tires. The T5 and the 7.5 rear end can not handle a lot of abuse.

If this car will be built toward street/strip use then the Eaton Posi or Yukon Dura Grip would be a good choice. If it will be built more for street and auto cross/road racing then the Truetrac or Torsen would be a good choice. All of these are available in 3 series with 28 splines. When you make your choice I can recommend a good supplier for the parts.
