Rear caliper brace options

Looking at the My Jota build thread has set me wondering..What are the pros and cons of bracing the rear caliper to the frame vs the swing arm. I have gsxr 1100 wheels with Reds adapter parts. Have yet to decide on a brace for the underslung Brembo caliper. I have owned bikes with both systems and have never been prompted to even consider the difference, but I can do either at this point . I think direct to the swing arm would look neater..wont be racing either..
Thanks

I have always believed (in other words, I'm happy to read a better explanation!!) that the benefits of the frame mount are that it neutralises the torque effect when braking; the brake doesn't affect the suspension. The rear wheel is less likely to chatter and using different connection points to create various angles can even build in pro-dive. Just posted a pic of my old system in Todd's Building My Jota thread. With that I could brake hard and definitely feel the bike squat and the geometry remain more neutral, rather than the usual front-end dive. I loved it. But I don't like powerful rear brakes either - mine will just slow the bike down and hold it at the lights.

Paul, I have both setup’s on bikes that I own. The 80 Jota has big wheels and an underslung caliper setup in an early drum brake twin swingarm that gives more clearance for the big tyres. That bike has the brace attached to the original fixing point on the swingarm. The othe bike has the arm mounted to the frame directly .

Thanks for both replies..I guess I,'ll try a couple of mock ups before doing anything permanent ..probably driven by aesthetics..as mentioned won't be racing..or even going get fast for very long. We need to lengthen the island.!
