I am still trying to decide on the suspension upgrade parts for my 12 LS.....On most things I am settled on but I really would like to know the physical differences between the 302R and 302S Rear lower control arms.
They appear quite similar in the pictures and description but there is a HUGE price difference.
I don't mind spending the extra money if it is really worth it but I am struggling with this decision..please advise.

OBTW..the rest of the list is M-5300-T SPRINGS
M-4264-A ADJ PAN HARD
M-5650-A LCA BRACKETS

Just need to decide between the R and S LCA's

I actually looked at the WHITELINE ADJUSTABLE LCA's also..decent price PLUS ADJUSTABILITY! I just don't anything about them or their products. Please chime in on opinions.
THANKS
Don

Thank you..apparently my oldman eyes couldn't pick that out.. I need an eye exam!

Haha! I know how that feels. But actually, unlike most of the other heim-jointed LCA, Ford's is designed a little differently and it isn't obvious. Maybe somebody here has a close-up photo. Gary runs the 302S LCA.

I have had my Whiteline LCA's on for about 20k miles or so and they are solid, no issues as of yet. I mostly DD the car but occasionally track it when I have the money. If it is a toss up between the FRPP with the bushings and the Whiteline I would go with Whiteline as they are adjustable and also very stout.

Too Hot for the Boss!
The S arms (M-5649-S) have spherical bearings.
The R arms (M-5649-R1) have poly bushings.

If you are going to drive your car on the street, you won't like the S arms.

However, if you do want them, I have a lightly used set sitting in my garage that I would love to sell
 
Finally made a decision..Thanks for the ionput!





I went with the follwing as I use my car MORE on the street than track days.Hopefully I will see benefits for both.
