Koni's are going to be more sporty, with quicker rebound. I wouldn't recommend them if you want a soft compliant ride. Why not OE tokicos? Koni FSD is another option that would be for daily driving and not harsh.

Ye i hear that fsport shocks are hard to find. So koni yellow, koni fsd, or fsport. I would prefer not to drop these, i would just run it with the stock springs. Can somebody give their experience or opinion.

Tirerack has KYB’s but I was wrong, koni only makes a sport shock for our cars, not the FSD.

Fsport shocks with stock springs are noticably harsher than stock shocks/springs. I don't recommend them for your situation. Fsport sway bars will nearly eliminate the body roll though...they really transform the cornering feel! I second the stock Tokico shock recommendation.

With coilovers you can adjust the stiffness/softness. Just get coilovers. And F Sport sway bars will decrease body roll, but not eliminate it. You'll need stiffer suspension minimize the roll even further (hence where coilovers come into play)

Koni FSD'd are discontinued for our cars as well, alongside the bilstein f-sports

+1 BC Racing BR Coilovers, there's a reason why they're so popular for our platform. With the standard BCR spring rates 10k/8k the ride is still very comfortable and you can adjust the harshness as you like. I'm pretty sure they are cheaper than replacement struts even if you have to replace the shock cartridge every 30k miles or so IIRC, but at least they are rebuildable

personally I am looking to get a Feal 441 max travel kit for my car. They don't list it as a compatible model on their website but I emailed them and they say they can build one no problem.
Reasons I am looking at this vs other entry level coilover
1. I can maintain stock height or slight raise for winter driving (I am in Canada and lots of snow here) with the ability to mildly lower for summer
2. Swift spring standard
3. Longer travel shock comparing to other brands (again, ****ty road)
4. Odi (the owner) is reputable in the suspension tuning crowd (from reading and talking to him)

Feal is all hush hush about their valving which is weird, people have said they are simply re-valved BC's, which could be good thing as the hardware on BC's is legit, but they should be more transparent.
