Honda still sells the sport suspension for 8th gen accords. Would the springs off of that setup work and fit the TL?

 

Accord is a bit lighter than the TL so the ride may not be the best, or might end up being softer. If you want firmer go with TL-S springs/shocks.

Beware aftermarket items are the same part for 04-08 TL & 03-07 accord so you might end up with something softer than factory suspension.

 

03-07 HFP suspension is LONG discontinued. I know because I had HFP suspension installed on my 07 Accord V6 and was not able to find replacement and this was 5 years ago now. I replaced with Tein Advanced.
