Cannot find a concrete answer... im thinking about putting drag radials on the z to cut down my 2.2 60ft time...worried about axle's snapping...or what axle would you recommend?

 

just make sure to preload. it will help with the life.

 

do explain?

 

I have stock axles. 1.60 60ft. 11.245@127.42, 540whp 436wtq, on full slicks, but I did try a set of drag radials before. I'm also very easy on my car.

Anybody can brake an axle, drag radials are very hard on axles with a 6 speed. Drag Radials work best for automatics.

You would be better off with an ET Street Bias Tire.

 

how are you easy on your car if you run an 11.2 lol?

So stock axle's last by chance only?

 

What I've learned from a lot of other car platforms is that drag radials or slicks can increase the life of half shafts, because drag tires reduce wheel hop which is what usually breaks half shafts.

 

well I only spin to clean off my tires (no wheel hop) everyonce in a while it i wheel hops if I break it loose in second down the track...but I do agree with that fact that wheel hop breaks them

 

I ran 10.0@138 on stock Ebay refurbished axles...I was making over 700hp with 1.50 60fts. I broke the Driveshaft shop 1000hp axles clean in half at 550hp and they refused to warranty them..(customer service is non existent in the import world but that is another topic.)

The key is stop the WHEEL HOP..If you get wheel hop your gonna break them in 2 or 3 passes.. simple as that.. I used all solid rear bushings with full slicks and never broke another axle, and was running refurbished stock ones...

 

Actually its not so much the tires as the suspension that causes the wheel hop. And you are more likely to snap an axle on a DR or slick than sock street tire. The street tire is just gonna light up and spin, where the slick or DR is gonna try and get traction and start hopping.. Once your suspension is dialed in, the wheel hop will be eliminated. I ran an adjustable coil over in the rear, raised up a little bit, with a firm dampening rate,solid rear bushings and adjustable camber arms.

 

guess I should take a break on drag racing, save up for a quaife lsd, solid diff bushings and et street drag tires... cause either way the diff needs dropped to do the diff bushings...

 

Dont do a Quaife LSD for the love of god, dont...I ran one for about 3-4 weeks, it couldnt hold up to the abuse and burnt up...All my fastest times were on a stock LSD and Stock axles believe it or not. If you must do a LSD, do the Nismo its more clunky but held up on our other car for over 2 years till the car got wrapped around a pole.

 

You sure it didn't burn up because of your 700 hp? I plan on supercharging in a year or so and stay under 400hp or whatever mark so I don't bend a rod ( use stock engines instead of building one) ... Your the first ive heard of burning up a quaife

 

I burnt it up in the 550Hp range, same HP I snapped the 1000hp drive shaft shop axles. I was only running low 11's at the time. If you have to have an LSD go Nismo.

 

^love my nismo... Annoying for slow street driving, excellent for track

 

so you would recommend a vlsd factory lsd over a quaife? this is my dd and I don't have thousands to throw at it all the time lol

 

Stock VLSD works just fine. This is what I have.

Also, it take money to play.

 

Then dont waste the money on an LSD. If you have a stock LSD already in your Z, dont waste the money on an aftermarket one, you will most likely never need it or notice that you need it. Put the $1000 elsewhere...In fact spending it on hookers and cocaine would probably be a better investment... My stock LSD was what I put back in after the aftermarket one went bad, and I ran low 10's all day and night with it..

 

im trying to snab a pumpkin with 4.08 gear, with spl solid bushings and either stock vlsd or aftermarket... and sell my bone stock pumpkin which is open diff....

thanks for the input guys...im still on the fence on to go cheap and get vlsd or go aftermarket...guess I will do more research in this library of madness

 

Unless you are racing professionally, then search no more than my last post. Or go waste your money on some fancy JDM rear diff and Ill be here to tell you "I told ya so"..

 

I have a used VLSD out of my car with about 45,000 miles on it, if your interested. bigest cost would be shipping. I'm not to far away, north Florida. Let me know if you want to work a deal.
