Karina, weight affects more than just quarter mile times. Straight line is passe. Drift is teh ghey. Real corners are good.
Yeah, I know that a stock TI can be quick in corners, it just takes a farking good driver. My completely stock TI ran away from the rest of the SA boys up a road I hadn't driven one night, and that was all the others in silo's and GX's with filter, exhaust, suspension and tyres... But now in the DR30, with bugger all extra power over stock I can get through a set of curves soooooooooooo much faster because the car is lighter and sticks to the road so much better.
I'm much happier with the DR than I was with the TI even though I don't like the round tail lights and other telltail Skyline bits that are on it or the Skyline stigma that goes with it. It's a bit quicker but feels so much better on the road, the only '31 I've been in that comes close is Shannons Pintara but thats got coilovers and new sway bars and stuff that I havent done with the '30
Fatz 4 door probably handles a shitload better because it doesnt have an anchor sitting in front of the front axles anymore.
And I reckon I could whup your 11 sec TI's from one hills town to another
