After trying different combos I’ve ended up with Cusco 25mm rear and Type R 23mm front, for me it is the sweet spot. My car is on the low side, I am on FA 500 coilovers with Swift 10/14k springs. It is a little on the firm side but handles and steers beautifully! I want to test the limits on the track but spirited driving, I am super happy finally. It is a little on the oversteer side but I like it a lot. Other than stock which was not bad for normal street driving and mild spirited driving but not stable enough at faster and harder cornering for me. tried 24/21 , better but I didn’t like the understeer 24/24 little better but steering still felt lazy on aggressive cornering although high speed bends was very stable and now 23/25 got me to stop experimenting for now anyway 😜. High speed is stable yet keeps me on my toes, aggressive cornering and S turns etc is an absolute blast 💥 , at first I thought perhaps a little on the oversteer side but now so used to it that I almost wouldn’t mind a little more at hard acceleration on very tight turns but that may be more due to my helical lsd as opposed to a clutch type or more aggressive pack. Have stuck with this set up for about a year and a half now ish. Once I track it if I don’t find that my rear end wants to let go against my liking then I’m absolutely sticking with! if it does seem to want to let loose then i may consider changing or start with raising my car a hair (I’m a victim of form over function sometimes since it is not a track car) but I am extremely happy with my DC5 right now! I’m right between that fine line of the look I like and performance I want to maintain ratio 😜

Installed on my 2002 Si. This is significantly larger/stronger than the OEM bar. Worth the money. I paired it with the truhart subframe brace and whiteline endlinks. Only hiccup I had was the bolts from the Truhart kit (the ones that attach the sway bar bushings to the brace/LCA) were not long enough to accommodate the aftermarket brace & larger sway bar . I used m8-1.25 30mm bolts from O'Reilly's and was able to get everything seated flush. The sway bar cleared my OEM muffler. Ride height is stock but much stiffer/less body roll.
