991.2 springs?

I scrape my stock base (whatever the non-S sport one is called) all the time. I can’t imagine being that much lower. I’d be destroying the nose of my car. I already feel like I take many entries slow and at crazy angles to minimize scraping. Next one will have front end lift, no doubt. I’ve seen the light!

Scraping
Definitely scrape more now, mainly on driveways. Speed bumps don't seem to be a problem and I haven't found any problems on roads including steep, twisty roads. Fortunately, I mostly drive this car on back roads, so I don't really encounter driveways that often.

Are the Eibach lower slightly than sPASM or slightly higher than sPASM?
Anyone know the spring rates of the Eibach or any of them for that matter?
what sway bars pair the best with above springs?
if I only want to start with one axle for the swaybars to start is rear the best?
what parts are needed to get full alignment with lowering springs.
for those wondering all three of the sleeve coilover conversions(HR, KW & ER) WILL NOT work with FAL (front axle lift).

You don't need to change swaybars. With bigger swaybars, your ride will suffer accordingly. DSC V3 works much better, firming up your PASM suspension as needed in aggressive driving and softening the ride in street driving. And it gives you the ability to fine tune the settings.
I didn't need any additional parts stock or aftermarket to do a full alignment since it's just slightly lower than SPASM. The shop was able to set camber a little more aggressive while setting everything else to specs. My cab is covered in storage mode at the moment so no pics.

thanks for all the responses... i had decided on the techarts, but right before ordering, changed gears and went with the H&Rs. Probably tear the front end off the car, but at least I'll be able to report back to the forum!

Those adjustable coilovers at Tirerack seem to be progressive springs, too. I was thinking of these from Elephant racing for a bit more: https://www.elephantracing.com/porsc...-kits-for-991/
Agree that the Techart can pogo stick a bit, but so far I don't think it's worse than the stock setup.

Also, sway bars do not affect the ride, they control the roll when cornering so it reduces the weight transfer. Tarett Engineering makes their own sway bars (GT Series) based on the GT3 bars.
TechArt will not release their spring rates and from the comments here the progressive rate is really soft. The H&R are progressive too but have a higher spring rate and thus a harder ride.

I'm going to go with the Elephant Racing coilover conversion kit for a few reasons. 1) they use linear springs 2) offer different spring rates 3) retain the PASM shocks and 4) bought the DSC V3 to stiffen the shocks for track days.

I've never felt this to be the case on every car I have swapped the bars. The shocks and springs primarily dampen the road imperfections. There is no load transfer to the other side with an independant suspension until the car leans as thru a corner.

I went with eibach because they are linear and from what I’ve heard about them will be the look I’m going fo and seem to be the stiffest offeringr. Will upgrade sway bars down the road. Hopeful for a decent alignment afterward.

Would love to hear your feedback once installed. This is an inexpensive upgrade (was surprised how cheap) and would like to lower and stiffen things up some...just not bone jarring....

The 991.2 base comes with PASM standard. Maybe you are thinking of PASM-sport?
I put the Techart springs on my 991.2 base and so far, I'm pretty happy with them. The ride is pretty close to stock and I would say the handling is somewhat worse in slow turns but somewhat better in high speed cornering.
The car dropped exactly 1" in the front and 3/4" in the rear. I added 10mm spacers in front to help prevent the "tucked in" look, though 15mm may be better.
The process took about 4 hours and went pretty smoothly based on some of the previous posts from this forum:
I drove it around for 3 weeks and then had the alignment done at the dealer--it wasn't that far off, though. While I was waiting, this GT2 RS was being prepped:
Really need to watch out for driveways now, though speed bumps seem okay for the most part. Here's the look now (yes, I still have orange reflectors):

Techart springs in gentle turns
I would say there is a bit more body roll in low speed cornering. Probably due to a lower spring rate in the first part of the spring travel. After driving on them a few months, I wouldn't say they are objectionable, but something you need to get used to.

Interesting. I always figured that lower springs would be stiffer all around, but I’ve heard people say the same as you. Now I’m wondering how my car compare to another equal model on stock PASM. Now it’s starting to make sense how I don’t feel my car is as stiff as I’d think it should be at lower speeds. But once pushed it tightens up real good.
