One of the only weak points on the 964 and 993 chassis is the engine carrier. When these models are tracked, or are fitted with stiffer than stock engine mounts, the engine carrier should be reinforced. If it is not, the carrier is known to bend, crack, or even break cleanly away from an engine mount in response to increased vibration and stress. The Porsche factory was aware of this problem and equipped its race cars with a reinforced engine carrier. Rennline now exclusively offers reinforced oem engine carriers. We procure oem engine carriers and reinforce them with our gusset kit for your convenience.

We try to hold an inventory of these reinforced mounts, although there may be times when these are unavailable. The price for a pre-welded mount is $325 including the core charge. As soon as we recieve your factory mount we will refund you $65 for a 964 carrier or $75 for a 993 carrier (cores must be in usuable or repairable condition).
