shooting for 11's
i have a question for all you guys…
so last season a post a best on my c5z at the track. here is my slip
r/t - .061
60' - 1.817
330 - 5.132
1/8 - 7.854
mph- 91.78
1000 - 10.160
1/4 - 12.109
mph- 115.51
now here is my question I'm lowered on stock bolts, i have long tube headers, black wing CAI, borla cat back, 275/40r17 and 305/30r18 nitto drag 555r, pro tuned. car made 393whp/390 ftlbs.
how can i adjust to break into high 11s. should i use a smaller tire? or would a 315/35r18 held a better 60' any experience is appreciated.

it just sucks cause were are so close but everything has to be "perfect". i just hate that with these tires you really need them to heat up otherwise you're not getting out of the trap fast enough.

Raise it back up a bit, we've found that lowering it hurts forward bite a good bit. You'll hook up a lot better if you aren't lowered all the way on the stock bolts.
Also what shocks are you using? The 04Z shocks really help forward acceleration.
You just need a bit more initial bite and you will be there. To cut a couple of tenths at the high end costs a lot more than getting off the line better.

If you are willing to put on a bias ply tire and some skinnies, this will be the easiest way. You could run 26x11.50x17 MT ET Streets on C5Z front wheels and GTO spares up front. You will need the skinnies since running a full size radial up front will be highly unstable with the bias ply rears. These tires will make it easier to cut a good 60'.
You can keep your current DRs and get your sixty down to a high 1.6 or low 1.7. This will take practice and technique along with a little track prep. A set of Hoosier 275x40x17 DRs on C5Z fronts are a much better combo. With practice, consistent 1.6s are achievable.
BTW- Concentrate on the first 330' since that is the most critical portion of the run and has the greatest effect on ET.

hmm where could i find a set of the gto spares? and that size hoosiers? i love drag racing been going since i was little also my uncle, cousin and i all have it out for each other lol all in good fun tho. but i figure ill learn the car first then really get into it. first time in a rear drive car also just got it last year as well. would the stock clutch and everything hold up to the hoosiers?
As for the GTO spares, I actually have a set that is painted to match the OEM wheels. They are mounted with M&H radial skinnies and I will sell them.

The stock clutch will be fine although an aftermarket clutch will work better. You may wish to hold off on that. The stock clutch and the Hoosiers are good for mid 1.6s.

hmmm, i just cant get over how ugly the gto spares look. i looked into a cow drag pack thats on the forum for sale. but i may just get some tires and see about working with this set up. ill raise the *** end up a little more. and work on technique. possibly a clutch. any suggestions on a clutch that you can still slip out of the hole and has good street manners?
We like an RPS twin. You would not need a full carbon billet BC2. You would be better off with their street twin which is half carbon and half organic. We cut mid 1.4s in a H/C C6 on 17" MT ET Streets with that clutch.
