That weight of 1370 kg is very close to the mark as I had to get a weighbridge ticket for my R33 for the blue slip to get her registered and she came in at 1372 kg in stock road trim.
Now that she is registered again my worry is that after the Brembo's, new intercooler, big exhaust, big radiator, GTR rear end, GTR body braces etc etc go in I will be up around 1400kg before Brad starts on the bolt in cage.
