Now im no track or suspension junkie, and i dont know if this is a repost, but i always noticed ppl always complain about spinning of the line at the track with street tire's (cant speak on DR or slicks) but have you ever thought that your suspension played more a part in spinning than you thought??? I've rode on stock, eibach, s-tech, and a current k-sport coilover setup, what really motivate me to write this is because i notice that with the coilovers on i very rearly spin if at all and i just got finished taking them off to send out and i thought lets see what WOT is like now when i did i spun through the whole 1st (automatic) from a dead stop no power break or roll, with the same situation with the coilovers i NEVER even chirped the tires, unless i power breaked, so IDK maybe instead of blaming the tires or how high you reved maybe its you spring shock setup and how much of a lift the car has when you accelerate when you WOT... Inputs accepted, i could be oh so wrong just my thoughts

 

I'm sure you've got the right idea. Notice these guys who are running 1.7-1.8 '60 foots are running coilovers or at least aircraft cables.

I'm working on setting up cables + drag bags inside my rear coils for max effect with the slicks. Hoping to get the fat old 5.5 running some deep 1.7s.

 

your definitely right. suspension does play a big role. whatever will keep the front down and weight on the front tires is great.

i don't have coilovers or cables and i've pulled 1.79 and many many 1.8xx. track prep is a big factor....

 

hmm, now to learn something... what are aircraft cables???...

 

agreed, track prep would help a lot

 

When I did my 1.58 60' I had an AGX on one side and a GR2 on the other side (the other AGX blew so I picked up a used GR2 at the U-Pick) with GC springs that were given to me with the struts. I had no tie downs (aircraft cables) they were taken off when I changed the strut because I totally removed the perches so there is nowhere to attach them.

So my whole front suspension as it sits only cost me $10 for the used GR2.

 

some ppl gets so lucky

 

My car never had traction problems at the track. Actaully I could almost never spin my tires when I went WOT on the street until I did my VI swap.

 

Anything that reduces the weight lifting off the front wheels will help but you can pull great 60' times without all that stuff too.

it's all about what you are willing to go through. Personally, I'm not willing to run a bunch of cables and spring blocks and all that stuff at the track. just not worth it to me.

 

I have pulled 1.7 60's with slicks and really haven't set my coilovers at all. i set the ride height and thats it.

 

my 4th gen had the problem, matter of fact, it still does

 

I have tried all that stuff and its not really required to get great 60's. All I have ran on the rear for the last couple of years are the GC's and AGX's that were given to me, no other mods.

On the front as I said earlier I did have tie downs which really don't make any difference in the ride and even they were removed for my last couple of races. I don't make any changes to my suspension at the track, only install the slicks.

I drive my car back and forth to the track which is 2 hours each way and its my DD so I do want it to ride somewhat comfortable. The only comfort item I have missed s the A/C and didn't even need that this year. I have my P/S back in and a couple of other comfort items that I had removed but it hasn't really made any difference in my times but my weight is creeping back up.

 

asin you're getting fat? just hire a midget to drive your car instant 150lbs of weight savings!

 

He's refferring to the addition of his PS etc.

 

oh...

 

wish they had GC's fo 5th gen....... 4x4 is killin me right now

 

Spinning off the line?

Haha, welcome to my world!

oooooooooo 15.3 with a y-pipe, no good... im faster with less mods (significant mods too) yea what are u lowered on???

 

Vogtland Springs, 1.3" drop, front and back = saggin' a$$ affect

So when I hit the gas the front lifts up and the rear squats badly, causing alot of tire spin. I have to hit the gas just right in order to keep it from spinning too much, but even then, I've never really had a good clean launch with this setup....(which is why I average a 2.4 60' most of the time w/a PB 2.354.)

If I had a set of good coilovers there's no doubt I'd be pulling 2.1's and 2.2's all day, and likely be in the 14.8-14.9 range consistently....because the power is definitely there.

As for you being faster with less mods, yeah, maybe at the track (for now)....but from a 20mph roll or more you can bet your a$$ I'd smoke you all day long, without a hitch.

And why do you act like I have way more mods than you, when you have everything that I have, only minus a y-pipe (and probably alot less weight)??? It isnt like our cars are so much differ, like you're trying to make it out to be. (and to be honest, I really didnt notice a huge difference when I switched out the y-pipe, like I did with the cat-back)



Also, as stated per my thread, the 15 sec timeslip database for 5th gen N/A 3.0's with similar setups, the average range for 60 ft's is 2.1-2.5 and run anywhere from 14.5-15.7's (Manuals & Auto's) with my current setup, or very similar. So just because you ran 15.049 (yet to see a timeslip that you said you'd post, btw) with a suspension setup that doesnt spin off the line, doesnt mean that's average for a stock setup or suspension like the one I currently have, with the saggin a$$. And IIRC, even the stock suspension from the factory has this same problem, with the saggin a** affect.

Not to mention, I have the boat anchor SE 17's with a tire/wheel combo weight of 55lbs a piece and have only run my car on a humid night where they didnt even prep the track (they only do that on Saturday nights, as I later found out, which I went on a Friday when the track was at its worst.)

And just for a reference of how bad the track really is, a friend of mine has a 5-speed 4th gen with Vias/00VI swap, intake, y-pipe, udp, no a/c unit, and a vafc-II with a rough tune, and only ran a PB 14.7 with 16 inch steelies on; and the only time he said he did that was when the track was fully prepped and hardly touched. The rest of the times he ran anywhere from 14.9's-15.2's, on a consistent. Maybe you just run on a better track?? (combine that with no spin off the line w/coilovers & I could see why you ran the time you "supposedly" ran.)

Also, how much does your car weigh on a digi??? Cause I notice your fog lights are removed in every pic, so it makes me wonder if you've removed anything else without telling us...(a/c, p/s, ect)....Currently, mine weighs 3360 on a digital scale with me in it and the spare tire removed, although I do have a sway bar, so that really negates the weight of removing the spare/jack.

So yeah, the point is, dont be so quick to jump to conclusions and peg someone as having a problem just because you ran an above average time, when there are just too many variables that play a factor in the 1/4 mile times, especially with traction (& weight) being two of the majors ones.

Although, I do think you learned a good lesson on how much traction really does play a part by removing your coilovers and testing out your suspension without them, so atleast you picked up on that...eh?

Certainly cant fault you for learning...

 

 

my car didnt spin the tire....instead i had terrible wheel hop.

 

to smokingmax, our cars are not different at all however the drivers in the car is.......... i had zero weight reduction when i beat ur times.... 15.1@92 and 15.04 with weight reduction,(600th of a sec, ooooooooooooou) i cant tell what the outcome would have been from a 20mph roll cause there would be no stopping points (of coarse u'd say race over the second u walk me in, which im still not sure u would) anyways seeing that u felt no difference in the y-pipe, care to trade + cash??? (thought so)... i agree with spinning cause i still spin, just not as much or as bad.......

 

if you look on my track vids on youtube....i had tokiko shocks spring set up there....i use to spin/wheelhop all of first gear! then i got coilovers and new tires....and went from a 15.2 to a 14.8.......the coilovers play a big role in it for sure... and for the guy in the post before mine.....EVERYTHING PLAYS A ROLE IN YOUR TIME! YOUR MODS, SUSPENTION, YOUR DRIVING, THE WEIGHT OF YOUR CAR, YOUR WEIGHT, TIRES, R/T, ETC......

 

I agree, i dont know what lead you to direct the comment specifically to me... anyways, yes you are 100% correct, the point of this thread is to let ppl know that you may have the same mods as someone else but they constantly runs better times, but ur car has no known problems, it could just be the suspension
