How big of a difference would there be in 1/4 mile times vs. stock 16's or 17's? I would think a couple of tenths would be lost because of the 20" rim. Also any ideas what a GS400 with SRT intake, Greddy exhaust and 20" rims would run? I say high 13's low 14's. He would have a better chance of running mid 13's with stock 16's and Drag Radials.

13s with 20s? man i dunno... i woudl think you would need more than just intake and exhaust. maybe MAYBE with 16s and drags you can brake 14 with GReddy and SRT, if you are a areally good driver... but its tough!

the GS4 is rated 14.3 with 17non chome most likely so, i'd guess 20's would put it to 14.6 maybe 14.5 then GReddy and SRT maybe 14.1 sorry dude i dont know, i think actually with 16s you may pull it off but i dont know much about power/weight/E.T. times sorry just tryin to help a little..

There is no way you will get in the 13's with 20's on even with intake, exhaust etc.. Also depending on how heavy your 20's will be is a big factor. I don't think you will even get in the low 14's honestly speaking.

That's what I was thinking. Somewhere in the 14's with the 20" rims. The only way for 13's is with stock rims and drag radials. But the best way would be go to the track and run the car..

Here is something I learned about unsprung weight, on my Supercharged Prowler which runs 12.7 at 112 mph i took off the run flats and put on SP9000's which are 11 lbs lighter per tire on the rear alone, helped me get into the 12's. I think for every lb on a wheel or tire is like adding 7 lbs to the car. On the g-tech it was 4/10 faster 0-60.

Just some food for thought.
