nazar Posted March 28, 2006 Share Posted March 28, 2006 Ok guys My setup is a 355ci lt1 with a cam and t56 tranny to a q45 vlsd rear end and mosler halfshafts I am running 275/40/17 sumitomo htrz tires out back on a 9.5" wheel Car is lowered, motor is mounted jtr style WHat are your predictions for my traction, both on the street and at the track? I am kinda kicking myself in the *** for not getting drag radials on those wheels instead of the sumitomos, but will i be surprised at the traction? Will it be pretty good with the setup I have off the line? Will i get traction in 2nd from a roll??? The car will be road worthy this weekend and I will be taking it around the block on its first trip this saturday!!! Quote Link to comment Share on other sites More sharing options...
Corzette Posted March 28, 2006 Share Posted March 28, 2006 With 40s in the rear assuming your pushing 300 or so to the rear wheels, I predict no traction what so ever! IMHO street tires plus low pros equals less traction.....keep us informed and please prove me wrong. Wait did you say T56? Def no traction....

jnewby Posted March 28, 2006 Share Posted March 28, 2006 dont worry you will probally have to replace those pretty soon anyway then you can put the drag radials on and maybe strip out some rear gears. Quote Link to comment Share on other sites More sharing options...
getZ Posted March 28, 2006 Share Posted March 28, 2006 If drag racing is your primary concern you can do a lot with suspension tuning. I'm always amazed when I read the corvette forum and see some of the 60ft times guys are cutting with a bone stock engine. My suggestion would be to get a g-tech or similar meter and kind of do a trial and error with clutch release. Some times the car may be bogging, but the alternative may be excessive tire spin. Keep an eye on your 60 ft times as they are key to tuning your launches. Of course a drag race suspension can be a compromise over a road handling suspension so finding a balance is what you may need to do.

The reason I say this is because I have the BBC Z with low pros 18s and man my 60 is like 3 secs no matter what and I have the T56. Corzette is another story. MTs and 1.5 60s. Suspension tuning is a must but you will need traction ready tires to aide in the best 60. Ask ZFAN abou that. Terry Quote Link to comment Share on other sites More sharing options...
Mikelly Posted March 28, 2006 Share Posted March 28, 2006 Let me give you a little comparison on my own problems with traction... This past weekend the asphault temps at the race track were in the 50s and the car I was driving is a 3250# C5 Corvette. On the back I had 295-35-18s and i'm running 3.42 gearing w/T56 and 386 Wheel HP/382#Ft. torque. I had limited traction at part throttle, but Zero at full throttle in 3rd gear. When I had my 383stroker T56 combo Zcar that weighed in 25XX pounds, I had some minimal traction issues as long as I didn't mash the pedal. But if you got stupid, it would be a smoke fest. I could break the tires loose from 3rd to 4th at over 100MPH for 10-20 feet or more and that was on a 265-50-15 Goodyear. Mike Quote Link to comment Share on other sites More sharing options...
nazar Posted March 28, 2006 Author Share Posted March 28, 2006 wow...shoulda got drag radials then huh ? For daily driving Damn.... I have an lt1 with all bolt ons, electric water pump, hotcam, 1.6 rockers, good exhaust and intake and no accessories, with tuning I am hoping to get about 340whp or so. Should have done the bfg 275/40/17 drag radials huh.... Quote Link to comment Share on other sites More sharing options...

Stay with street legal tires if you go softer. Maybe buy an extra rear set of rims and tires for the special ocassions.... Terry Quote Link to comment Share on other sites More sharing options...
nazar Posted March 28, 2006 Author Share Posted March 28, 2006 yea i really wanted the 17" drag radials for street use, and probably would have been good enough at the track, now im stuck with sumitomo street tires and i know they wont hook at the track or on the street We'll see I guess, I may just get some 15" wheels and slicks for the track, but on the street my 17"s are still gonna be problamatic i think Quote Link to comment Share on other sites More sharing options...

With a chunky 15" drag radial you should be able to get some serious traction. Who cares about the awkward look at the track anyway? Hey, the Hondas with the steelies look worse...

ziptieracer Posted April 1, 2006 Share Posted April 1, 2006 if you end up going with drag radials, try the mickey thompson's. me and my buddies all used to run bfg's. my one friend with a supercharged goat switched over to the m/t radials and dropped 2 tenths off his sixties consistent. he said they made the bfg's feel like regular street tires. he's cutting 1.6's iirc with m/t radials the same size as your sumis. car is stock weight, no suspension mods. just a high stall converter and the m/t's. food for thought.

silicone boy Posted April 1, 2006 Share Posted April 1, 2006 Ha Ha Ha. He's just fishing for compliments. Reminds me of a supermodelesque girl I went out with one time who asked, "Do you think I'm pretty?", knowing full well what the answer would be.

Guest ON3GO Posted April 1, 2006 Share Posted April 1, 2006 the bfg drag radails that have the crazy thread pattern SUCK! get nitto's if need be in the lower offset style drag radials. the better bfg drags come in the thicker side wall, same with the good M/T drag radials. my dads bone stock Z06 cant catch traction 1st, 2nd, and will step out in 3rd hard with traction control off... its damn fun but you will get passed if you look like ur going down a ice rink! he has some 295-35-18's on the back, and i made good and sure i had them hot and sticky before i went balls to the walls. my blue Z is getting a pretty wicked turbo LS1 and im considering running a really meaty sidewall drag radial all the time, wont look as cool as a nice low profile wheel but i wanna go fast! mike Quote Link to comment Share on other sites More sharing options...
