Bilstein B16
Front 399 lbin
Rear 423 lbin

The Bilstein rear number seems low to me but that's what I found. If anyone has another number lmk and I'll update.
Ohlins on my 987.2 are 400 and 430. They are stiff but I love them and want to marry them.

Update... I ended up taking a slightly different approach than I originally intended but I think this will be a a fun way to evaluate different products

1. I got a very nice deal on a used DSC V2. Going to install this first.

2. I purchased Joec500 used Techart springs for a great price, and going to evaluate from there. If I am happy I will leave them, and maybe go for Bilstein's or used GT3 coilovers next season. If not, nothing really lost, I can resell or something. I am doing installation myself so no loss there.

I had this EXACT setup previous on my car with multiple track days and canyon runs. It's fantastic for the price. Just make sure you install the right firmware for your car. I was running the 911 turbo setup and the car never ran right, as I didn't realize the previous owner had a 991.1 Turbo

Oooo good to know. I know that I will need to "zero out" the DSC ride height once its installed. I will check on the firmware/software. It is coming from a 991.1 GT3.

PM'ed definitely interested in the springs.
Actually if you get creative with a spring compressor you can actually compress the spring while still installed on the car and move that snap ring...ASK ME HOW I KNOW

I know another user here has the 991.1 GT3 in his car (991.1GTS) and he loves that map. Try that map first before switching it out.

Yes, please do. I'm getting my TechArts installed today and have been thinking about the DCS controller. It seems like the consensus is for daily street driving only helps with bumpy or poor roads.

Need some help verifying something...

Techart springs include new bump stops, are they for front or rear?

H&R springs include new bump stops, are they for front or rear?

My impression is rear, but than I saw a DIY spring install post for H&R springs and guy put them on the front.

Are you guys SURE Techart springs are made by Eibach and not H&R?

I was looking for assistance with bump stops on PN 091.200.120.009 (991.1 C2S), I can't figure out what they are speccing for my need, page 5, "2 - 991.343.301.05 - Helper spring FA" BUT for some of the models they spec "28880 VA-Z" which is an H&R bump stop. My spidey sense (8 years of working in performance automotive industry) is telling me Techart springs are actually H&R........

I figured out bump stops. Techart uses OEM PASM-S bump stops for 991.1 C2S, and they go on the front. Guess I don't need to buy any.

99134330105 = 991.343.301.05

Front stock

Rear stock
