Eibach Pro kit vs Sportline

[krummel45]

I was wondering how much performance is lost when going from the sportline to the pro kit, because i am draging my exhaust every once in a while and i dont want to rip anything off.

How much will i sacrafice by changing over?


thanks

False premise.

The car will handle better.

Yeah I don't think it'll handle worse, just the ride height won't be so low and as bouncy. You can only go so low until it starts affecting performance.

The resulting higher center of gravity and higher roll center will make it handle worse.

 

[2GeNTSi]

true but I don't think there will be a significant change in handling.

 

[igs]

true the difference is not that big

We've been through this before, igs, so I'm just going to give my opinion and walk away.

Yes, CG height makes a difference, as do the heights of RCs. But suspension travel makes a much bigger difference. And Sportlines are too low for their rates, which causes you to bottom out the front suspension, sending the effective spring rate through the roof, causing a lousy ride and lots of understeer.

That's why switching from Sportlines to Prokits will make the car handle better.

Bottoming out is a big no-no. The instructions tell you to cut the bumpstops which you should do if you are bottoming out.

I know about performance but i was wondering if the height difference between the two really makes a difference?

 

[jtmcinder]

My car has 500# front springs, which is probably around 50% stiffer than a Sportline front spring. My car is not lowered as far as a car on Sportlines. I have Koni Sports and trimmed bumpstops. And, even on my MXs, I bottom out the outside front when there's a moderate bump in the middle of a hard corner.

Yes, Sportlines - being that low combined with that soft - will hurt performance. To be really blunt, anyone that says otherwise is either on super-short front shocks or isn't driving anywhere close to the limit on realistic surfaces. In other words, given that this forum is about performance and no-one seems to run Sportlines and super-short shocks or Sportlines on perfectly flat surfaces, Sportlines should only be mentioned with the same kind of derision that we normally reserve for Hondas with coffee-can exhausts.

ROTF

Get a coil over kit and raise the shock mounting point with higher plates.

Run stiffer springs.

Change exhaust systems or just the muffler...

I'll have to take pics of my bosal system after the drop and swaybar install.... It hangs high.. Lets put it this way it is an oval muffler and the sway bar crosses below the inlet !

It's about using parts that work with the whole package.

Those shocks are long in the body... Which means you need to move the bearing plate.

Also lowering spring rates are usually too soft and the quality poor... Actually the eibach 2.5" x 7" that come with GC's are pretty poor too.

Not too sure about the 2g, but on a 1g the pro kit hardly lowers the car at all. I would go sportline.

I dunno if I'd agree with that. Sure, the ProKits don't lower it a lot - so you still have some fender gap - but you can definitely tell the car is lowered compared to stock. Plus, although lowering a car does look better, the realistic goal should be performance, and as previously mentioned, the Prokits are preferred over the Sportlines in that regard. So, it looks decent w/ Prokits, and it's not too low that you're running your bumper up on every driveway (only about 1/3 of them )
