968 Turbo RS Style Aero Wiper Deflector for Porsche 924, 944, 944 S2, 944 turbo (951)


In 1992, Porsche introduced the 968 Turbo RS race car in order to compete in the new ADAC GT racing series in Germany. This racer was based on the 968 coupe with only limited weight optimization only due to the regulations of the series which had a 4kg/bhp power/weight ratio limit. The Turbo RS featured a KKK K27 turbo boosting the 3liter 4-cylinder engine using an 8-valve head - similar to the cylinder head of the 944 Turbo S - rather than the 16-valve standard N/A 968 head. This powerplant produced an output of 350 bhp which was far below the power level it could have achieved.

European weather played the biggest part in Porsche’s development of the Aero Windscreen Deflector which was designed to help eliminate wiper lift at high speeds encountered on the race circuits. This is a problem that most cars featuring a ‘low profile windscreen rake’ suffer as passing air gets under the blades at speed and lifts the blades slightly creating a ‘hovercraft’ effect. This then leads to poor visibility at speeds over 60-70mph.

RSR9 have reproduced the Turbo RS Aero Wiper Deflector and have slightly modified it to fit perfectly to all Porsche 924, 944, 951/2, and 944 S2 models. The screen deflector works by deflecting the air upwards towards the edge of the bonnets trailing edge. This helps drive the air resistant’s in an upward fashion eliminating much of the wind resistance which normally gets under the wiper blades.

This product which is exclusive to RSR9 weighs little (less than 1.5 kg) and is manufactured to a high standard in FRP (Fibreglass) and supplied in a white gel-coat ready to prime and paint. It fits against the bonnet perfectly (both base and rear edge) ensuring that no air will get under the deflector.

Mounting the product can be achieved with various techniques and we have tested using double sided ‘3M Automotive Tape’ (recommended) or using a few lines of windscreen silicon black sealant.

For-reinstalling wiper jets we recommend to mount washer jets onto the wiper arms (which we have found to be the best option using the same jets as fitted to the new Mercedes Sprinter Van).

Production lead time (if not in stock) is approx. 10 working days from payment.
