Why Choose Us

Straightline Performance was established in 2003. Having appeared on Speed Channel's highly rated "Pinks", twice, and various other racing DVDs such as Scandalous Racing's "You Got the Hit," Straightline Performance has become the choice for those wanting serious power with the time slips to prove it!   We are here to do ALL of your installs/custom work as well. We have built/worked on everything from your average street car to 1000+hp racecars, and although we are primarily a "Domestic" shop, we have built a few fast imports as well.  Most importantly, though, you can rest assured that when you bring your car in, be it for an oil change or a full build, we will treat it as if it were our own. Cars are our passion, and we will do everything in our power to make sure you come into the shop and leave happy.


Straightline Performance occupies 11,000sqft of shop space in Joliet, Illinois, just 5 minutes from Chicagoland's premier racing facilities, Route 66 Raceway and Chicagoland Speedway in Joliet.
