Porsche 911 GT1 Special Guide

To comply with homologation requirements, Porsche built two street versions of their 1996 Le Mans contender. These pre-production cars are essentially the same as the race version without all the safety equipment, a higher ride height and more interior amenities. The two street versions were actually built in 1995 as 1996 model year cars. The engines were slightly detuned from 600 bhp to 544 and the gear ratios were changed. Read More
