The best part is that the 6.2 Chevy V8 is mated to a gated six-speed manual, because why the hell not?

Sin is a British company racing in the GT Cup Championship with their own race car, the GTB, driven by company boss Rosen Daskalov. They are also developing a GT4-class car at the moment, but in the meantime, they managed to cook up the GTB's sister car, the road-legal R1 GT.

What you're looking at here is a tubular space frame chassis based on their FIA homologated T45 version with carbon composite panels inside and out, pushrod double-wishbone suspension with one way adjustable shocks, AP Racing's 362 mm discs with 6 piston calipers and 376 cu.in LS3 crate engine producing 450 horsepower and 317 lb ft of torque mated to a six-speed manual and a mechanical limited-slip differential.

Think hardcore Lotus Exige for about $110,000. Sin says they are ready to build up to 120 annually using some Bulgarian carbon fiber...

For your money, Sin is giving you 2,535 pounds worth of road-legal racing technology with an optional sequential or semi – automatic gear box if you prefer that instead of the manual.

The R1 GT will reach 60mph in 3.5 seconds, 120mph in 9.7 and keep going up to 186mph depending on the gearing.

Does that sound like a track day/occasional grocery getter dream come true, or would you rather spend your money on a Lotus Exige S with quite a bit of gas money left in the bank?
