Seat Thread Color Question (silly!), and Suspension!

[Stiglitz]

Hello all!
I am about to pull trigger on a set of Lseat covers for my 2002 986.
My sillly question has to do with the tread color.
I have bog standard Black seats.
The thread color appears to be a gray/white (darker after 20 some odd years?)

Anyone that may have purchased black lseat covers, what color did you choose for the thread?
I don't want it to look out of place.

I'm also pondering having the upholstery shop put in seat heater elements "while they are in there", and just leave wiring bundled under the seat, and I'd take care of wiring.

Odd that I am asking suspension question also.
Think I need tie rod/control arm on driver's front side.

I'm trying to stay at budget on my projects....
I'm thinking of getting major components (coffin arm, tie rod, control arm) and have shop install (to avoid the markup!). And think I'm reallly only budgeted to do one side (not the entire front).

Thoughts? (w/o flaming?).

Also, for those curious, local upholstery shop (Winter Park/Orlando FL area) has quited me $120 per side to put the covers on.

Thanks in advance.
