The product is praised for its excellent fit, usability & installation simplicity. It efficiently adapts from flathead to standard and T5 transmissions, supporting various clutch setups. Superior to Offenhauser kit, it is commended for impeccable quality and fitting 'like a glove.' Some customers wished for inclusion of a metric stud. Its compatibility with multiple flywheel and master cylinder sizes is highlighted, while proving effective even with parts not recommended by Speedway, enhancing its practicality. Also, recommends including metric studs.

Bolted right up - no problem. Hydraulic clutch installation instructions were excellent. Speedway recommends the use of a 3/4 inch bore master cylinder but tried it out with my existing (5/8 inch bore) master cylinder and it works fine. fyi: I used the clutch disk and pressure plate from the doner S10 that I got the T5 transmission from - just had to drill and tap the flathead flywheel to accept the pressure plate.

The stud holes in a Borg Warner T-5 transmission are M8 (metric) and you only supply 5/16 and 3/8 studs. I thing the metric stud should be included as now I have to drive 30 miles round trip to get a metric bolt to make into a similar stud.

Great part, fantastically made part no need for the Offenhauser kit unless you want the name. fits like a glove. Easy to install with many options for clutch set ups in case I'm not happy with hydraulic throughout bearing. Only thing I didn't like was the hydraulic throughout bearing uses a #2 A/N fitting and didn't like using conversion fittings. But not a big deal
