I bought 2 16x8 z28 rims and was planning to put a set of 26x10.5 MT ET slicks on them. For weeks my dad and I have been arguing that I will throw the rear end out of it by doing so (stock rearend). I have a relatively small stall and will plan to launch it at 2500 rpms at the track. I was basically wondering if there should be any worries with such a soft launch. I'm done for this year in terms of going to the track, but next year i plan to go there more often like every other weekend or every third weekend and will hopefully have 450-475 rwhp.

Any thoughts for concern or just go for it?
Thanks

 

Running MT drag radials and before that BFG Drag radials. The rearend has 137k miles on it. The fluid has been changed a few times but seems to be doing well. Not all are created equal though....

 

what are you launching it at and thats funny you say that...my car just rolled 137k yesterday *stock rearend*. also how many runs have u put on and do your tires hold well at the track?

 

Well I used to have a vig3200 and then broke it and restalled to 2800. I leave at 2000-2500. As far as number of passes....maybe 75? Normally on 1.7 60'. I have seen the MT drag radials run 9.99 by a friend, that's why I chose them. The rearend has been pretty good, but you never know! Check my video below.....

 

I understand what your saying with the smaller stall.. But, on slicks your going to hook, I wouldn't do a 2400 stall either.. might as well go higher if your going to gamble..

 

right now i have a 2800 as well. last time i was at the track i was running shitty 2.05 60's because i was on street tires (obviously). So i wanted to have a good street tire and then once at the track swap over to the slicks. I'll be buying the new tires soon and mounting over winter. i'm down at school so the car will be parked shortly unfortunately. I don't plan to launch over 2500 since the stall comes in at 2800 but any time i tried launching at 2k it just smokes em' resulting in bad 60's and a frustrated me. haha but thanks for the input guys

 

Dont be affraid to run slicks on that 10 bolt. I race my camaro every saturday on slicks and sometimes I do a nitrous launch depending on the car I'm spotting. I 60ft 1.58-1.64 on motor and best nitrous launch on a 50 shot was 1.53. I bent the rim screws on that launch, I thought 4 screws on front and back of rim would hold it but they didn't.

Tell you'r dad, it's a auto car not a stick. it's not like your going to dump the clutch at 7,200rpms. The rear end will have a load on it when you bring the converter up. you will be ok, first time I ran my camaro at the track when it was stock was with a set of m/t et drags on it, and I had a hour ride home.

 

Roided...what brand of stall do you have?

 

I've launched at least 250 times on radials, bias-plys, and at varying RPMs ( flashed, not flashed ).

I've only ruined two Torsens so far. ( Got a Tru-Trac in there now ), but never killed the gears or axles. This is with a 3.73 ratio.

Whether or not the rear will crap depends on a variety of factors, and nobody can predict when it'll let loose.

Good luck.

FWIW, I'm planning on spraying my way to low 1.5x's/high 1.4x's in the near future ( early October ), and I'm still on a ten-bolt.

Car has been mid-11's with lots of low 1.6x's and a few high 1.5x's.

EDIT: I also wanted to add that bias-plys *should* be a little more gentle than radials, due to the larger sidewall... A little more "give" in them, if you will...

 

I have a 3200 stall and i've sprayed 175 off the line at 2700rpm with my 26x11.5-16 ET Streets and i haven't had a single problem yet. That little 10 bolt should be fine.

On a side note, i happen to have a pair of 26x11.5-16 ET Streets for sale that only have 1 pass on them they're in the classified section, just saying.

 

You'll be fine. An auto car will load the rear end, and with the bias ply tire, that will take even more absorbtion out of the initial shock of the launch.

 

man you guys have been really helpful.
01SOMZ28 i saw your add a few days ago and it appealed to me a bit, but i literally just bought some 16x8 z28 rims. unless you would want to do a trade or somesort id like to get 100 for both....so if ur listing ur rims for what i believe was 400? we could maybe figure something out. just pm me.

i always say its an auto and will "load" but he's stubborn so I wanted to just get a definite answer from all you guys that have plenty of experience.

Camaro396, how do you like how your stangs tires hook for an everyday tire? I wouldn't mind getting a set of those for the next rims i get =)

 

Must you have tubes with with et street dot slicks? or will it be okay without? Sorry, not trying to hijack the thread, just a quick question.

 

nah good question bro, i'm a noob to the whole racing scene i guess and don't mind getting some more facts under my belt

 

You don't *have* to. They're an option.

I ran mine for a while without any before I switched to radials.

 

I like the BFG drag radials on the Cobra, however I wouldn't want to DD them. They would suck in the rain, and be bald in a month. I have like 300 miles on mine, and they need replaced.

 

I'm not running any tubes in mine.

me and you also need to line'em up next time you're in Lincoln.

 

ouch, thats a short life expectancy lol. I'm sure your driving tendencies may have some effect on that haha but whats the point in having a toy and not beating on it. Next spring i'll hopefully be buying a set of 18" rpm 505's and then having the rears widened so expect more DD tire questions next spring! lol but I will be ordering a set of slicks late fall I appreciate all the input from you guys.

 

i have a 3500 yank and I'm also running ET streets mounted on Zr1 17x11's stock rear 150 shot on the streets car hooks great no problems here.

 

I would think that dead hooking on a radial would be even harder on the rear end than a bias ply. Bias ply has sidewall give, where as a radial does not. I have a 4000 stall and I launch at about 1500rpm and it dead hooks on the stock 10 bolt 123k miles.
