whats cookin good lookins
As I am only 7k miles into my 60k warranty I don’t necessarily want to get a ktuner just yet. Well, obviously I do but I’m trying to play safe as long as I can. Just wondering what mods you’d recommend to give me some better performance or what you’d recommend anyway. So far I have a Perrin strut bar, whiteline rear sway bar/ end links, and a torque solution rmm. I know I should obviously get some grippy tires and probably lowering springs (I don’t necessarily want to shuck out a ton on Coilovers just yet)

I agree with lightweight wheels. I noticed a significant difference when I upgraded. My wheels are 18lbs/wheel opposed to the 29lb stockers.

Go ahead and upgrade your clutch before you tune to get ahead of the game. CTR retrofit should be on every si wishlist.
Is the modification to the ctr clutch fairly simple? I was thinking about a lighter clutch a little down the road

ALready have whiteline sway bar, it feels awesome hitting highway exit ramps. The whiteline endlinks were a pain in the ass for me to find the right fitting for, and even still after buckling everything up I know something went wrong so I’m gonna I’ve someone else look at em. Should’ve went with accords endlinks

I’m definitely thinking about at least the shifter bushings but I may as well just get the whole setup which comes with everything correct?

Do you happen to know the accord end links p/n? I want to make sure I get the right one.

Lighter wheels and upgrade the intercooler
Is an intercooler upgrade really necessary if you're mostly (80% of the time) using the Si for normal commuting (i.e. shifting @ ~3-3.5k rpm using only light throttle to accelerate) and 20% / rest of the time is spirited driving / WOT above 3k rpm?

I went to Torque Solutions to look for the rear motor mount that you mentioned, but couldn't find it. Could you post a link?

I did Type R shifter with base bushings, centering spring, and rocker. It feels very smooth and precise

I got this package minus the cable bushings. I'll be getting them later
