whats the difference in 1/4mile time?

 

what model are you asking about?

 

In general the sedan is about ~100 to 150 lbs heavier. That would be .1-.2 secs slower

 

Definitely depends on if you're using the 4-Dr GSR or any other 4-Dr submodel.

 

sorry, i ment... 4door GSR vs 2door GSR

 

yea. for each ~80 pounds = .1 sec slower.
as for wheels.. 1 pound off the wheel(s)* ~ 40 pounds off cabin/chassis. (i've read)
*i'm not sure if it that means off all four wheels or just one.

so the stock AVG. gsr time is around 15.3 soo expect ~15.5 from a sedan

 

i dont think stock gsrs are runnin 15.3s. atleast not on street tires. im sure its been done with a freak motor but i wouldnt say its average. id say more like 15.5 for 2door 15.7 for 4door

 

yeah, its hard to get a good time in southern california. you hear about GSR's in other parts of the country running low 15s and what not, but out here, with the lack of good tracks, its hard to stab a good time.

You're asking for GSR times, so i dont think i'm much help to u...but i'll try anyway. My first try out in fontana almost 2 years ago, i got 4 runs 16.87, 16.83, 16.44, and 16.72. Bone stock pretty much, ghetto intake, crappy exhaust, crappy tires, crappy suspension, full interior. the 16.44 and the 16.72 i ran against another coupe LS, and beat him both times.

Zoom ahead to December of 2002, and my suspension setup is much better, still crappy tires though, empty interior, better intake/exhaust, but still pretty much stock....i only got 3 runs, i blew the first run spinning off the line, but the second and third runs i got a 16.33 @ 85 and then a 16.17 @ 87, with R/T's in the lower half of .500 seconds (woohoo!). The 16.33 the dude next to me snapped his axle, and the 16.17 was against another LS coupe that ran a 16. 4 something. i kno i kno, 85 and 87 trap speeds equate to high 15's, but with 2.5 60 foots, i wont be hitting a 15 any time soon. nonetheless, for an otherwise stock 4 door LS, low 16s are still impressive to SOME people...

Overall, coupe versus sedan, its a pretty small difference, yeah, its .1 or .2 seconds, but that .1 or .2 seconds can be made up by experience or track conditions.

 

GSR sedan should be hitting mid to high 15s depending on whether its stock or with boltons.

 

well i was about to say 15.5 but then i decided to factor in the obd1 gsr's [94-95] that have been known to run 14.9 to low 15's bone stock.
