hows it going well i have a 2000 trans am thats only putting down 405hp and 375tq i have all umi suspension that include panhard bar lower control arms and a adj torque arm thats set at -3..

im also have a 1.5 drop using Eibach springs with adj kyb shocks.. i have a strange s60 with 4.10s and brand new nitto 555r but the dam thing wont hook to save its life does anyone have any opinions on what else i can do or if theres anything i should change

 

a4 or m6?

 

also what tire pressure are you trying to hook at?

how big of a burn out?

what rpm are you leaving at?

do you have 60ft times or you referring to the street?

 

sorry guys its a m6 at the track w/line lock so iv been doing big burnouts

iv tried 20 18 15 12 and 10 psi on the tires

my 60ft times are always around 2.0 to 2.2

iv tried launching at all rpms

 

At the track in a a4 car with similar suspension set up aside from rear end and gears I pulled 1.7 with less hp then you.

Try setting the t/a to -2. Also are your lca adjustable? I have my lowers set at 19 1/2" ish from center bolt to center bolt. Do you use lca brackets?

I also noticed that the stiffer I set my rears (qa1) the better the times. It was hard for me to break the old skool 'squatting is better belief' but the numbers don't lie. The tighter the rear the better the 60 for me.

You have all the equipment it sounds like, now it is just time to fine tune your set up.

My best advise to you when it comes to adjustments, is small adjustments make a HUGE difference!

 

no my lca are fixed ill stiffen up the shocks and adjust the tq arm to -2

 

555r or 555r drag radials ?

the kyb adj. are better than stock but not much,look at their price.
set them as stiff as possible.

are you using lca relocation brackets ?

with 4.10s',good biting tires,& suspension,you should be able to easily get 1.8s'

being that 555rs' are a radial,lowering pressure won't help much as you'll be loosing center contact pressure. try in the normal pressure range.

 

Also how much seat time do you have in the car? M6's are VERY hard to launch (compared to a4) and this can account for alot of time left on the table! If you are newer to the m6 world practice practice practice.

 

there the drag radials and no i dont have the relocate brackets.. are the qa1s my best choice to go with? no i have a lot of experience with a m6 but this car has never liked to hook up idk why my other trans am had the same exact set up but had stock springs and that thing would hook like no other

 

For the rears I have QA1's but alot of guys seem to like the Afco and strange rear adjustable shocks. I like my QA1's and for the price I couldn't go wrong.

 

it's difficult to tell someone to spend money on expensive parts.

does/did the strange s60 come with a setup of a set of holes for repositioning the LCAs ?
if not,are they adaptable to be able to use LCA ReLos ?

I'm running double adjustable QA1s' and the ability to individually adjust/set compression and rebound is great,but they're expensive compared to the single adjustable.

 

Did we talk yet? The only mechanical thing missing seems like relocation brackets.

Like mentioned above, small adjustments make a big difference. Take lots of notes.

 

This thread is pointless. There are way too many variables.

 

lca relocation brackets would deff help alot with how much the car is lowered but you also never said what size nittos you were running...

 

+1 on relocation brackets. Those will help a lot since you are lowered1.5 inches
