IMS Rotating Assembly Kit W/ARP 625+ Rods For 8V/8S Audi RS3/TTRS

Iroz Motorsport Rotating Assembly Kit, featuring our 7-second Rs3 internals. These pistons and rods are engineered for ultimate durability and power, transforming your street car with racetrack-tested performance.

After working with Diamond for the last year, we are proud to release the exact same internals we have in our record cars.  We built these pistons with cam offerings in mind and they have been proven in not only the Rs3/TTRS world, but in Road Racing formats in the KTM X-BOW GT2.  What separates our spec from other offerings?

• Slightly lower compression at 9.62:1 (8cc) vs the factory 9.95(5.75cc)
• Iroz Spec top 1.5mm top rings with Napier 2nds
• Redesigned Cam Barrel for minimum rock at TDC/BDC
• 22mm wrist pins for more ring land material
• Gas ported
• Reliefs for even the largest cam opportunities
• Coupled with BoostLine 625ARP connecting rods, this is a combination we have gone into the 7s with at over 182mph.
• While the ring packs to add some cost, we feel like this is a massive upgrade for engines that will be pushed to their limits, in both factory liner or sleeved applications.
• We really love these pistons on street cars that see some pump fuel, especially west coast cars that see a lot of 91 octane fuels, with very little lost power on Ethanol based fuel and an expanded tuning window.
• ACL coated rod bearings are still our go to!
