That's a great video. I believe the SPF is just one step under the Kirkham. I really need to get a ride in one versus my LSC. DO NOT listen to the idiots that were talked about by SPO1715, they don't know what the crap their talking about !
Question- how well does the IRS hold up to high torque and drag racing ?
I've always questioned the reliability of the knuckles, shafts ect. I'm not talking about up to speed road racing but, dumping the clutch at a stop or say,.....10 mph up.
Thank you for the video !
