2G FWD Launch

[pur97tsifwd]

what is good suspension mods for a fwd to help it launch better i own a 97 tsi fwd?

 

[hustleman]

i would say semi- hard shocks in rear semi-med in front and some good tires that would really help..like bfgs drags and if u got a little cash a lsd.

LSD would really help your launch, 2 is better than 1 But thats not really suspension, thats drivetrain. Anything to keep your pressure on the front end and keep the momentum from shifting as much as possible. How bout some 6" AirShocks? j/k! But I would agree with a slightly harder setting in the rear. Get some adjustable struts and some good progressive rate springs and go nuts! Also depends, are you talkin drag or autocross, what driving style do you want to setup for.

Slicks will help more than anything.

What about adjusting your Tire PSI?

I've heard of people lowering the psi in their rear tires when they get up to the 300-500hp range.

Is this important for a 200-300hp range? or is it more of a FWD vs AWD Issue?

Slicks will help more than anything.

Although not the best option for daily driving...

Here's my list of the top mods for FWD traction:
1. A set of nice, sticky tires (Z rated performance tires)/slicks for the track
2. A limited slip differential (LSD)
3. Aftermarket (Prothane, etc.) engine mounts/solid, all-metal front motor mount
4. Lowering springs and shocks in the front (more downforce=more traction)*

*Lowering the rear will nullify this effect.

This is exactly what I run.

Here's what I run to attain 1.7 60's in my 2.3L FWD.

1. Mickey Thompson 24.5x8x15 Slicks on Aero rims.
2. A KarKing ATB Diff, just like a Quiafe
3. Full Prothane's
4. KYB AGX w/ Eibach Pro Kits in the front, rears are stock.

Ha, I like your signature... it applies to this thread.

Sorry but what do you mean when you say lowering the rear will nullify the effect??
Does that mean help the effect or worse? Not familur with that word
Also I have heard that stiffer motor mounts help because the engine doesnt snarl back.

 

[VelocitàPaola]

Lowering the rear won't help the effect. By lowering only the front, you make the car into somewhat of a triangle shape, or a "reverse airplane wing." This means air rushing by the car pushes it downward, helping to create more traction. If you lower the front and the back, the entire car maintains it's stock "rectangle" shape, just at a lower height. This configuration, just like the stock configuration, doesn't create any extra downforce; hence, only lower the front...

Stiffer engine mounts help by forcing the engine to deliver more of its power to the wheels. When you launch hard with your stock engine mounts, a portion of the rotational energy being exerted by the engine gets transferred into the engine mounts because they're so flexible. By replacing the engine mounts with stiffer ones (or better yet, solid metal mounts), less energy gets absorbed into the mounts themselves, and more energy gets transferred to the axles, and then the wheels.

So I wonder is that probably why the fwd srt-4 has that angled stance like that. I actually like that stance ive tried to do it with putting bigger tires in back but I didnt like the handling upon myself doing that. Not a bad tip though on getting better traction.

 

[VelocitàPaola]

I think they did that with the SRT-4 mostly for styling... they were trying to give it the look of those older, suped up muscle cars. I know lowering the front is definitely better for drag racing, but for all around handling, I'm not so sure. If I were doing AutoX or something, I would stick with a mild drop all around, not just the front.

 

[project_tsi]

With the rear being higher does help w/ more weight on the front, its still important to get a stiff setup of shocks for the rear so it doesn't squat. Like I said earlier, I still have stock rear's, but they really need updating w/ some stiffies. You should see my track runs, the rear end squats to shit.

 

[nightspeed87]

my rear ones are blown, my car bounces because my front ones bottom out too because i still have stock struts on a lowered car, that was dropped like 2 inches, and these struts were brand new and went bad in less than a couple month of hard cornering and etc. My car is so sloppy right now, it makes sense what you guys are saying, and Im not surprised you gain acceleration just from having a really tight suspension. Ive tried the srt-4 look with the front lower and It does not help cornering at all, that stance to me only felt good on launching, but I like to corner hard and keep my car agile not just for straight line performance so I cant do that set up, even though I like the way it makes the car look. Like somewhat a pouncing stance.

 

[girlieracr4g63]

I run GR2s in the front with lowered springs, and AGXs in the rear on full stiff. Keeping the car like these guys said, to what I like to call raked. Giving it a wedge look. This setup with slicks of course and an insert has gotten me 1.6 60s several times. Also the more weight you remove from the rear is going to make a difference as well. The idea is to have all the weight in the front of the car. There should be a pic in my profile showing how the car looks.

I have a 90 Eclipse GS 2.0....i just wanted to know what the "proper" way to launch my fwd car with the limited power that I have....obviously laying tire isn't too much to worry about when i launch unlike most of the powerful cars on this site haha...also, I wanted to know just out of curiosity how to do a burnout with a fwd...The only time I'm ever going to do this is when replacing tires but I just would like to know how to do it the right way as well and also, does it hurt anything besides the tires?

 

[Semprini]

does it hurt anything besides the tires?

If youre popping the clutch to do it then everything in your driveline... clutch, tranny, axles... Why do you wanna do this anyway? I wouldnt recommend it, whether you need new tires or not. I would do this with my GSXR1000 but that isnt the same. Its not worth trashing your car

 

[xRichieRich07x]

like i said...its not something I want to do and if I would ever do it it would only be if i was getting new tires...and thats why I was asking if it hurt anything besides your tires...I just simply was curious of how to do it in a FWD

Oh ok... Just rev it up and pop the clutch, theyll spin. You shouldnt need too much rpm tho, but yeah itll do some damage over time, depending on the existing wear on the car and all.

 

[sureshot971]

WTF Not too sure, maybe there should be a tech about this

 

[xRichieRich07x]

haha yeah thanks I know how to get them to spin for a second...but a burnout is keeping them spinning while the car basically stays stationary...besides that was just my secondary question from my curiosity...My main question was the proper way to launch my car..thanks though

 

[sureshot971]

It all kind of depends what kind of Hp and stuff you are running, normally to launch my FWD i just hold it at 3500 rpms and ease of the clutch while giving it more gas then normal, but i also have a turbo so its probably quite a bit diffrent.

yeah that's the thing I'm running around 145-150 HP max...I'm sure it's different from the more powerful cars

 

[welfle18]

i had a ford probe se just pulled the hand brake and dropped the clutch wouldnt recommend this!!!! its was a trashed car....

yeah defineatly no pulling my super old hand brake haha
