Eibachs or RD sport springs.....

[SIIK2NR]

I need info on RD Sport Springs!

I`ve narrowed down my search to Eibachs and RD sport springs. Can anyone chime in w/pictures of your drop on either and the spring rates for the RD sport?

I don`t know $hit about the RD sports and want to make sure that going with the Eibachs is the way to go.

Personally, I`ve seen the Eibach drop and I would prefer a little more in the front. I`ve seen the RD sport drop and it looks perfect.

However, I`m not willing to give up that much comfort and reliability for looks in the event that the RD sports ride like crap.

Inputs/experiences are greatly appreciated.

I got my RD sport springs because i saw that it gave the best drop from the front. Yes you need to be more careful while ur on the road but the car looks aggressive with these psrings on. I personally like them. As for the ride quality...to be honest its as if i didn't change the springs. comfort is still there... .

The only reason i would get Eibachs if the hight of the car is causing me problems with the streets im in. but so far so good...

Im happy with RD sport .

Get Eibach. Period.

RDSport's drop is way too aggressive and will ruin your ride and handling.

Lowering springs have been discussed to death here on the forum. Do some

Eibach for springs. If you want to go any lower, it'd be better to go with coils.

Thanks....

Actually I did research and search. "RD" wasn`t getting me anything and "sport springs" was getting me Everything.....

Appreciate the feedback.

Eibachs it is.

Here read this thread. Make sure you focus on the numbers because that is key.

Me personally like the rd drops look better also but I will not sacrifice wear and tear, ride, and performance above looks.

What about combining the RD Sports with the Bilstein Sport shocks? Would this help negate the fact of these springs being "lower" than the others? I have yet to really hear any feedback regarding these shocks...seeing as RD Sport uses them in their kit but charges a much larger sum ironically.

Also curious if you know the springrates for the Eibachs? I assume RD Sport springrates will always remain a secret but in the past Eibach has always designed progressive springs that are usually softer initially than OEM. Even though the rear is progressive from the factory I would prefer a springrate that is proportionally stiffer to amount being lowered if that makes sense. I am coming from custom valved Ohlins DFV's in my Evo so any standard spring kit has me very leery to say the least.

I've had both H&R and now Eibachs. Eibachs are much better. H&Rs were too squirrely at high cruising speeds and felt like. EDC is like stock (or what I remember of stock).

Also just tracked my car for the first time and found that the Springs did nicely.

That's funny cause your looking at springs at the opposite of the spectrum. It's like comparing the gintani race exhaust with dinan.

Lowering Springs won't affect your EDC.

You can fit eibach's and thats what i would suggest you put over anything else.

How much should it cost to get the springs fitted, as i have had quotes from $170-$470... just to fit them...

[SIIK2NR]

^^ Free if you do it yourself.

$200 is pretty fair price. You have to figure most mechanics charge $80-$100 per hour labor. 2 hour install, do the math.

$470 is robbery.

I do respect the time and effort you have taken with a couple of your suspension threads, but blanket statements like the one above is absolutely false. There is no evidence to prove it, and these kind of statements have been flying around the aftermarket world for years and often times it's blown out o proportion.

I am sure nobody wants to damage their beloved cars, but that is not the case with mild lowering springs. Yes, RDSports are pretty much mild springs as well. Bump stops should always be addressed no matter how little or aggressively you tamper with the suspension.

There is a ton of technical terms I can begin to spit out, but it won't make sense to the guys that want a simple answer. Will it ruin the car's balance and suspension if you lower it with springs? No it will not.

Secondly, why did you sell your Red M3 for a black one?

Saying that you know otherwise but everyone else is too stupid to understand it doesn't really help anyone either. If you got something to say, just come out a say it. Anyone who really understands the material should be able to dumb it down to layman's terms for us simple people to understand.

My sincere apologies. That is not how I meant it at all. What I was basically trying to say is that I can go into a lot of technical terms and so forth, but its not necessary as simple words will suffice.

Nobody here is stupid if they have an M3.

So what exactly is your take on all of this. IMO, opinion, the effort others have made to show what is potentially happening when springs are installed is admirable but there are too many generalizations and assumptions being made. There are so many variables in how the suspension as a whole reacts to changes that its very difficult to come to any kind of definitive conclusions just by measuring clearances and bump stop lengths. As of right now, I don't think anyone can say for sure what will happen in the long term when replacing springs. In a case like this, only time will tell unless someone attempts to do a very complicated and involved analysis of the dynamics of the OEM suspension.
