Ok I have a base 07 TL and purchased the H&R lowering sport springs from an 07 type S member. I didn't think about this at first and now that I have the springs, I realized its for the type S.

Anyways can I put these springs on for the regular TL? Are the springs for type S and base TL different sizes? I do see different part numbers for the base and type S. 50104 is base and 50106 is type S.

 

They're both exactly the same.

 

Well, except for the part numbers.

I guess.


OP - they will "fit", but the way H&R numbers and describes their parts there is no way for the average buyer tell by looking at the fitment guide if they are exactly the same or not.

 

ok thx

 

Old thread, I know. I had a similar question though so I contacted TireRack who in turn contacted H&R (from what I was told) and this is the information I received:

"The difference is in the spring rate and type of wire used. The exact specifications they consider proprietary, however the difference comes from the fundamental differences in the cars-The Type S has a larger engine and more agressive suspension rates. They are not transferrable. Consequently, if you have the Type S you do not want the normal TL variant. Obviously the reverse is also true."
