Measurements of Lowered Boxsters

[boxs2000]

My car measures at 24 7/8" in the front and rear. This is measuring from the ground up through the center of of the rims to the bottom of the fender. For reference, I'm running eibach pro springs with the factory Bilstien shocks with Bridgestone S02's at 225/40/18 and 265/35/18 in the rears. This set up is about 3 years old so the suspension is well settled in.

Out of curiosity what kind of coilovers are you running?

if you want a car that handles great & is primarily driven on the street, you absolutely cannot beat (for price or performance or comfort) the M030 setup (the car in my sig is M030 ride height). if you absolutely have to have the car lower, go for eibach springs & M030 everything else. if you have to go REALLY low, go for H&R springs & M030 everything else.

i've driven almost every conceivable combination of sways, springs & shocks available for this car & have come to the realization that (suprise) porsche knows what they're doing. unless you have some reason to need a car that's hyper stiff & squeezes out that last bit of performance for a street car, i am adamant that the M030 is most properly tuned option you can get for our cars.

the car on the left is M030; the car on the right is H&R.

M30 everything else? would be M030 sway bars and struts. Right?
Are there different M030 Struts or just the standard Bilstens?


Thanks

here's my preferred setup for a street boxster:

Front Sway: M030 'S'
Rear Sway: M030 'Base'
Springs: M030
Struts: Bilstein Sport or M030

the reason for the base rear sway is that it's thicker than the S and takes out some understeer. a primary reason i love the M030 springs is that while Eibach and H&R lower the car evenly, the M030 lower the car more up front. again, this takes out understeer.

the bilstein sport (and HD; they're damped the same) are supposedly a bit more stiff than the M030, but i can't tell the difference. either is great.

the eibach sways are almost identical to the M030 listed above, but twice the price. the H&R sways are WAY too stiff for the street and will be underdamped by M030 or Bilstein struts; your car will porpoise.

Essentially, if you buy the full M030 kit and have them swap the front bar to the S M030, you will have a full package that works very, very well together.

Insite, curious as to whether you have adjusted camber/toe, or have left those settings stock as well? And if you have adjusted, are you using after-market adjustable camber plates and/or adjustable links in back? I agree with your setup, and certainly don't want my car any lower, but am wondering how to get my tire wear more even (and contact patch larger) when i track my car...

thanks,

i run -1.0 deg camber up front on the street and -1.6 deg on the track. i set front toe to zero at -1.0 deg camber. when i change the camber for the track, i leave the toe alone. this pushes the front toe out a teeny bit, which i like on the track.

in back, i don't yet have any toe correction arms installed. i run zero toe at -2.4 deg camber on the street and on slower tracks. i set slight toe in for faster tracks. this is too much camber for a street tire, but i can't de-camber further without trashing my toe settings. this is of course cured w/ toe arms.

I have h&r race springs on my acura integra. its very bumpy ride, but the stance is perfect. I'm thinking I'm not going to put the h&r's on my porsche because of the bumpiness.

I would be interested in the stock porsche equipment if I can find the for about the same prices as aftermarket stuff.

This seems like a great idea. All OEM equipment but I will do the H&Rs or Elibachs. I had Elibachs at one time and may go back to them but the possibly lower H&R are tempting.

Thanks for the help, I should have thought of this on my own but I didn't I guess thats what you guys are here for.

sounds like you are moving away from the coilovers to the M030. i'm doing the opposite since i see the track a lot. want to work out some kind of trade?

just realized your first post mentioned you really liked the low look of your car. if that's the case, you want the H&R. i don't have the measurements handy, but they lower the car quite a bit. if boxs2000's car is 24-7/8 with the eibach pro, you'd be at your current ride height with the H&R.

the H&R are a little stiffer than the M030, but not much. i would go with the bilstein sport struts since they're supposedly valved a little stiffer than the M030; this will balance out the stiffer springs. don't even consider sway bars other than M030 for what you're looking to do.

My car is 24.5 so there is less than a half inch between the two.
Does anyone have H & R's can you measure for me??

As of today I am running KSport coilovers.
