Boxster's are not burnout friendly and definately not Tip boxsters with 2.5L engines. The boxster has a bad tendency to "wheel hop" or others call it axle tramp. If I slip the clutch and use the gas aliittle to aggressively the back end will bounce like no other. This isn't good for the car and should be avoided. However, when I am just cruising about 15-20mph and just step on it hard the back tires lose traction and step out a bit which is a cool feeling. The car can also do donuts well. I just keep it in first and turn the wheel a bit(open parking lot recammended) and give it alot of gas. A lot of tire smoking fun then begins! Of couse, this is much easier to do with a manual and alittle more power.
have fun.
