No BS just quality parts shipped on time Im currently swapping an LS3 into a 93 Rx7. Ive spent over 30 thousand dollars in 2 weeks. Improved Racin was the ONLY business that promptly shipped my parts, didn't screw up the order, or had some screwup holding up my project. Extremely satisfied.

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.

Excellent Products, Fast Shipping This is one of a few vendors of automotive parts (Fore, Radium, Science of Speed also come to mind) who sell unique, high-quality parts and has a fantastic staff to back them up. I had a problem with a couple of orders placed back to back because I was in a hurry and ordered the wrong things. They fixed them both, combined them to save shipping charges, and shipped everything that same day. I have bought a handful of things from Improved Racing and they are always well packaged, well documented, and look fantastic.

Great Product, and great customer service! Ordering from abroad (Greece), Improved Racing answered every one of my e-mails and questions almost immediately. They gave me good advice on my setup, (before and after I placed my order) and I cant wait to get the thermostat plumbed into my oil cooler setup. Also the thermostat was posted ASAP, and I received my order here in Greece only a few days after ordering. Great stuff! Will definitely be using them again!

Oil pan baffle and crank scraper I recently installed the LS3 Corvette oil pan kit with the Improved Racing oil pan baffle and crank scraper. I am impressed with the quality of the baffle and crank scrapper. They shipped the kit very quickly. I had to make a slight modification to one area of the scrapper to avoid interference on my engine but I simply followed the supplied directions.
