I have Hal shocks on all 4 corners of the car. Right now the front end is sitting pretty low <img src="gr_tounge.gif" border="0">



How much effect does this have on traction? Would it be worth the effort with that stupid spanner wrench to raise it up a bit???

Thx

Leave it. You give the front suspension more range of motion at launch with it lower. I think this is better.

My front is about even with the rear now so I plan on lowering it a couple of inches.

but with it lower...doesn't it pull some of the initial weight off the rear tires? I'm still having traction issues getting the 28x11.5x15 QTPs to hook <img src="gr_sad.gif" border="0">

It seemed to hook just as good if not better back when the front was up at stock height on smaller 26x8x16 ET Drags <img src="images/icons/confused.gif" border="0">

With the front end higher, yes, you are preloading your rear tires just a little bit more. But, I was thinking the same way about this and asked Jay Billingsley what he thought and he said for me to lower my front end. Maybe having it higher is better for initial hook (the first couple of feet) but having it lower is better after that since the body doesn't have to pick up the unsprung weight as quickly.

Do you have the rear spring cushions removed? I think I made a mistake by removing mine. This lowered my LCA angle. They are now reinstalled and I feel that it has helped a bit.

JS...every car seems different...best thing is to fit them up first and see what is needed <img src="gr_stretch.gif" border="0">

its the initial bite that hurts me...the car likes to wrap the tires 1-2 times then hooks. Its a bit harder to hook a hard clutch-grabbin' M6 <img src="gr_grin.gif" border="0">

I'll try raising it up a bit and decide if that works out for me <img src="gr_stretch.gif" border="0">

Fire, how do you have your suspension set up?

I have front hals, no rears yet. I found that one change in the fronts makes a pretty big difference for me, at 2/2 one day I hooked a 1.51 and then at 3/3 I was like 1.55's and spinning for 5 feet.

I'm putting on rears and I am thinking I will try 2/2 in front and 4/4 in back... I'm not going to 28's I think I can cut some 1.4's with my 26's.

I have my rear cushions out otherwise my car would be way to high in the back.

well I had a slight issue with a leaky shock <img src="gr_images/icons/wink.gif" border="0">

so I'm at 0/0 <img src="gr_images/icons/wink.gif" border="0">

I had one rebuilt for the same reason with the used pair I had...

I'm glad to hear this Colonel. My front end is damn low right now <img src="gr_stretch.gif" border="0">

i dont think it should hurt that much. i have mine a little too low too and dont have much of a traction issue. FYI dont use that POS spanner wrench. get a huge plumbers wrench, it will be much easier and you wont bust your knuckles as bad.

I'm about to oder new slicks.Do u guys think the 28X9X15 will hit at the bottem of my 1/4 panel?I know w/the 28X11.5X15 u had to shorten your control arms Brian because it was close.Do u think I'll be to shorten mine w/a 28X9 setup or will it clear.Circ. is 86in. on the M/T Et Drag if u need to know the dimension.

I could just buy the 27X11.5X15 QTP but I think the Drag will hook better.HELP!!!

I agree with the front end hight. If your having traction problems maybe raising a bit will help..but not too hight as you want the suspension to be able to work. Now..can we talk about the rear end hight. I knwo that you want to get the rear end out of the air as much as possble on top end too. Expecially TA's with the wing etc. Its just drag and will slow you down. Which is better ..the bite off the line or less drag on the big end? My spring rubber is removed. But I think I solved my traction issues I was having. I snapped my output shaft on my T-56 this weekend. I changed to a floating torque arm/pete-z setup with hoosier 28x10s. Broke my tranny first pass.

there's still that issue of initial tire shock in the M6 that might call for more preload (higher front end)

as for the spanner wrench...we welded an extension bar on ours <img src="gr_grin.gif" border="0">

Fireball, Dump the QTPs and go with a real slick.

Even a 28x9x15 full size slick would hook better than the QTP and your tractor gears.
Cheers,

I dunno about all that <img src="gr_images/icons/wink.gif" border="0">

(at least the 9" hooking better than my 10" tread)

Colonel

I agree. I think a 9" full slick will outhook a 10" street slick. Just baseing this on how much difference it made going from 26x11.5x16 Et Streets to 26x10x15 Hoosiers (the Hoosiers were actually wider dispite the 10" designation.)

It will make a HUGE difference.
Lots of guys running LOW 1.3's on a 28x9 inch slick.
No comparision and you will be consistent.
