So I pretty much have a bone stock (besides an Apr intake) 2018 TTRS and have been starting to go to track days and it seems like the engine has plenty of power at the moment for my skill level. I am wanting to add some upgrades and am thinking the suspension might currently be the weakest link. It's the one thing that doesn't feel very responsive.
Does anyone have advice for some suspension parts I should get? I don't want to get rid of the actual struts because of the adjustable ride stuff it does, figured aftermarket would lose that. Are there things like control arms, toe arms, dogbone mount, trailing arms going to make much difference on the track?
Any and all advice appreciated!

Did some more research this morning reading up on the Ohlins Road and Track coilovers - and maybe my concerns about the dynamic ride control are irrelevant as I would still be able to adjust them when going to the track or doing autocross.
Does anyone have recommendations on adjustable coilovers?

Before you start modding. It is best to get track experience with an instructor. Driver mod is huge.
For tracking I highly recommend you start with track pads Like Hawk DTC-60, a second set of wheels and track tires, with an alignment that gives you a little more camber. Those mods combined with all you have learned from instruction will be very big. I would also put a stage 1 tune on the motor just because its fun.
So, instruction will give you proper technique and allow you to go faster vs just trying to go fast.
The enhanced braking and the tires to back up the brakes will let you brake much later coming in to the turns.
The softer track tires will hold in cornering much better and by giving them extra camber they will sit flater on the pavement when you are cornering,
And do switch to high temp brake fluid like Castrol SRF.
That is my suggestion on where to start before you start changing bushing and struts. The TTRS is already a very capable car. After having modified many a car I have a lot of regrets about ruining the ride in pursuit of better handling..

Should be lots of learning this year. I've had 2 events already and one was a 3 day event hpde (gridlife) which the instructor was awesome. Next month I'm running with NASA which I heard has really good instruction.
I went with some camber/caster mounts plates from 034 on the front struts from 034 which increased my camber by 1.5 degrees and caster 1.0 degrees. Hoping that helps a bit cause when I ran Nelson ledges it ate up my tires, especially the front left.
I also got their rear sway bar upgrade and rear sway bar end links, and the lowering springs. Heading to Nelson ledges again this weekend so I'm excited to see how the changes feel.
Ps I'm currently running Michelin sport cup 2s so seems like it doesn't get much better than those but they're pricey. I bought another set but nankang ns-2r this time to save some money for once the sport cup 2s are toasted.
I think my next upgrade will be more camber cause I have been seeing others trying to get to 3 or 3.5 degrees which mine will only adjust up to about 2.5 at the moment. So thinking the lower control arms and ball joints from 034. Should give me the ability to get up to 4 degrees so should have plenty of room.
