Whats up guys and gals, I am looking to get some H&R springs for my 02 TL-S. I have 2 different part #'s and need to know which are the ones that will work for my car. 50103 and 51858 These are the 2 and I need to know which will work?

 

The 51858's are for the 99-01 TL. The 50103's are for the 02-03 TL. Acura changed something to make the car heavier in the rear so using hte 99-01 TL springs will cause the springs to sag a little more than they should. So H&R introduced the 50103 to compensate for this.

 

will either work well on the 99-01 then?

 

the 51858 if i remember right were designed for the accord and worked for the TL H&R changed to a heavier rate cause the TL is heavier. ( i believe thats what i remember reading a few years ago)

 

I would use the 50103
