Since I don't have any spring rates specs on kw, renntech,weistec, or h&r, I'm leaning towards h&r since it's likely the most comfortable. My car has the p71 dynamic package so it already has the stiffer suspension.
How many lb ft of torque did you use for the new extended lugs? Did you use the MB recommended 133 ?
Correct.

Thank you,

These are expensive, but what I went with. If nothing else you can use their lengths to determine how long yours need to be when ordering from someone else, though I can't remember who all sells them. Might try calling up H&R.
I’m seeing this a lot more lately where the retail price on anything it’s just so exaggerated that the sale price is what they normally sell for online. Lotta gouging going on now but these seem like quality bolts.
Update: spoke with H&R and they recommended 13mm front and 15mm rear for the GTS. Also recommended 43mm wheel bolts all around assuming stock wheel bolts are 29mm long.
13mm: 2655665
15mm: 3055665
Wheel bolts: 1454302 x 20
note that you can get the black version of everything above by adding "sw" to the end of the part number.
total was around $350 shipped to los angeles.
I read through every post and couldn't find a definitive answer.
If I order 5mm front/ 15mm rear spacers which wheel bolts will I need to buy? Are ours tapered or rounded? I apologize if this is just a stupid question.
Here's a pic of the stock set up I have just in case it makes a difference.

Stock lugs are 29mm - the general rule of thumb would be to lengthen from there the size of the spacer that you are using. So for your 5mm spacer, you should use a lug 34mm - there is quite a bit of tolerance behind the hub though if you had something *slightly* longer. Stock wheels for the GT use ball seating, but the lug itself is unique (it looks a lot like Porsche stock lugs); I not sure why the design is different...thats a code I havent cracked. I would think any 12x1.5 would work, but the design is different than other MBs.

Thanks for the info! I updated my post after a call with H&R. They recommended me a wheel bolts that were 14 x 1.5... are you sure its 12 x 1.5?
TBH you may be right. Most MB are m14 but I had thought the GT was different. I have a set of m14x1.5 off of a Porsche I owned. I’ll compare and report back!

same pitch and size as the Porsche m14x1.5 (GT on the right in the picture).
