Need advice on parts to replace suspension on 07 mz3

I've finally decided to get a proper mechanic to replace whole bunch of parts on my 07 mz3 s. I was planning on doing the work myself but life and other things got in the way. Now I've got a new job out of town and I'll probably be putting about 40k kms on my car every year until its time for something new.

Note: theres 190k kms on the clock right now (i've put on 25k kms in the last six months with the new job.
AND all suspension parts are original since new...

So what I've got so far:
Koni str.t shocks/stuts for front and back
1 x Left (part# 8750 1087l)
1 x Right (part# 8750 1087r)
2 x Rear (part# 8050 1107)
Top hats to go with the rears - 2 x Dorman Part# 924-412 Upper Shock Mount

Mazda genuine parts from Tasca (for front suspension):
2 x Front stabilizer link/swaybar link (Part# BP4K-34-170D)
4 x Dust cover nut/swaybar end lnk nut (Part# 9994-01-000)
2 x Suspension mount/seat (part# B39D-34-380A)
2 x bumper (part# BP4K-34-111C)
1 x Left LCA (part# C513-34-350)
1 x Right LCA (part# C513-34-300)

Am I missing anything for the front suspension ?

Mazda genuine parts from Tasca (for rear suspension):
2 x suspension stabilizer/rear swaybar end link (part# BP4K-28-170H)
2 x stabilizer link nut (part# 9YB1-01-005)

Not sure why I only ordered these parts for the rear...am I missing anything?
Would it not be a good idea to get:

1 x Left rear upper control arm (part# BBM2-28-C10)
1 x Right rear upper control arm (part# BBM2-28-C10)
1 x Left rear lower control arm (part# BBM2-28-300D)
1 x Right rear lower control arm (part# BBM2-28-300D)
2 x lateral arms (part# BBM2-28-500A)
1 x Left trailing arm (part# B35P-28-250)
1 x Right trailing arm (part# B35P-28-200)

Please let me know what you guys think. Greatly appreciated!

I have nearly 190,000 *miles* on my 04 3, and the only thing I have replaced are the struts, shocks, rear wheel bearings and rear lateral arms. Everything else on my car is still in great shape. Hell, I even reused my front strut mounts, they were so good.

Thanks for your input! Guess I should order some lateral arms as well then.

When did you replace your wheel bearings? I'm guessing mine are probably due sometime soon. not sure how expensive that job is going to be.

Don't go replacing parts just because. That's pissing away good money replacing stuff that is still perfectly serviceable. Only replace them if they're actually worn. I did my rear wheel bearings about 2 years ago after they started howling. I guess that was about 160,000 miles or so.

If and when you do do wheel bearings, before you order them, verify whether or not your car has ABS, because the bearings are different. Physically pull the wheel off and look for the wire. I assumed my car did, but it does not. I made them work anyway, but if I would have just ordered the correct thing to begin with, I wouldn't have had to redneck engineer a fix for my glitch.

Bearings are cheap. Like $50 each. The Lateral links were like $20 each.

I really like Bilstein over Koni tbh n I had konis but if your control arms aren't bad don't replace em just inspect them I'd be more concerned. On your rear suspicion like trailing arm bushings, use your common sense n just CHECK everything no need to fix something that's not broken

my car went into the garage on Thursday, they said it would be ready by Tues noon hopefully (in Canada Monday is holiday and this particular garage doesn't open on the weekend).

Replacing all shocks/ struts with Koni oranges, new front LCAs, new end link (front and back) new stabilizer bushings (front and back), new spring seats, etc - just want this car to be back the way I bought it(I have done ZERO suspension repairs / maintenance since my 07mz3 was new and now theres 195k kms on it......about 30 thousand that I have put on in the last 8 months). - I drive about 120kms / day at least, sometimes more for work and want the car to last a couple more years before something else comes along.
