Quick Suspension Questions

[tonythetiger]

so, researching the suspension parts to swap out on 100K 2001 Boxster S and ran across something odd in lower control arm description at my parts retailer website. I saw mention of self-leveling suspension for litronic headlamps???
I see the back suspension and it looks normal using 99634105317 lower control arm, but I have litronic headlights...is the suspension different for the front of this car,
note: I have a 2000 boxster s with halogens and know that car uses 4 - 99634105317, is it different for a car with litronics? just wanted to ask you smart folks.

also, symptoms taking me to suspension refresh are...rattling/clunking at low speed, when i gas it it goes away. hard to isolate at the shop

Thanks
