When we tested our Drakan Spyder on the track we discovered oil starvation of the LS3 was a problem. Our oil pressure was dropping into single digits. We called Improved Racing and tested their baffle system that fits into the stock oil pan. After installation, our oil pressures, under the same conditions with the same pro driver, did not drop below 25psi. It proved to be the perfect fix!

Transmission thermostat is awesome. Service from Improved Racing was great. Quick delivery of a very high quality piece. I ordered a fluid thermostat with -6 fittings for a 10 sec bracket racer. It arrived in 2 days. After installation, my 60ft times, that had varied by 2 hundredths, now only vary by a few thousandths. Temp stays right at 165 as advertised.

Just wanted to say that you guys are the best place I've called in 2 years for tech support! I work at a performance shop and search parts everyday. Service was excelent thank you!

If you are looking for quality products and people that actually stand behind them you found the right people to deal with!

All products exceeded my expectations, I am so happy I decided to order from you guys.
