Hi Robert,
A stock 1974 S3 tested into a slight headwind achieved the following - no debate, this is fact !
0-30mph = 3.3 secs
0-60mph = 6.4 secs
0-90mph = 14.0 secs
Standing start one quarter mile = 14.10 secs @ 91.0 mph.
Top speed on a restricted straight = 103.3 mph. DEVASTATINGLY FAST FOR A MERE 400 IN 1974. To see 110 on the clocks was an easy achievement. The S3`s in fact had a far better top end speed than the admired RD 400 Yamaha. The latter however would pass at fuel stops!!
I have much detailed info. on brake specs so clarification of your exact needs would be useful, however -
Shoe lining thickness = 5mm. Service limit 2mm.
Shoe spring length = 56mm. Service limit = 59mm.
Front disc thickness = 7mm. Service limit 5.5mm.
Disc runout = 0mm. Service limit = 0.3mm.
I hope all this helps,
Very best regards,
Dave.
