1st gen ecx circuit getting a well overdue upgrade

So way back In 2013 I bought my nephew a 1st gen ecx circuit (2nd version, I say this because it was 2.4ghz instead of an am system). The pics attached are how little he was when he opened the car for his birthday and now holding my daughter being taller then myself lol. Anyways Six years on the thing has been through the ringer with outstanding durability. In that span a front shock broke, back tires are bald and slightly unglued, receiver broke (water damage) and that’s it. We did although make some minor changes we put in a new receiver/new remote (the spektrum system that came with my stock arrma senton 3s blx ) a new esc (this was only changed because we wanted to run lipos for some reason I thought the stock one couldn’t or wouldn’t allow for that I could be wrong and last but not least we changed the 20t motor to a 15t motor. ** o and added a 2s 5000mah 30c lipo** .

Now for the upgrading part it’s been a long time since this rig has had some love. so I’ve decided to upgrade heres the list of what I’ve bought so far:

-rcawd aluminum big bore shocks front and back
-rcawd Aluminum a arms front and back
- rcawd aluminum rear shock tower
- rcawd aluminum hubs
- hpi tires and rims (don’t remember names basically stock tires for hpi firestorm 10t)
-rcawd steel steering links/pull rods
-rcawd metal rear driveshafts
- ecx 9001 (metal gear transmission gears
- surpass hobby 3650kv brushless motor esc combo 60amp esc up to 3s lipo

So as you can tell if you’ve made it this far I’m going for a brushless set up and my question to the community is am I missing anything in a brushless setup ? Are their any weak points I should address other then the ones I have addressed ?

Welcome @Fabio casa! I don't see it listed anywhere as already replaced or potential mod, so I'd recommend getting a metal geared steering servo and RPM servo saver eliminator. Those are a great way to tighten and strengthen up your steering.

Good point I was thinking of the servo I’m probably going to do that because I believe the stock one is all plastic gears

So UPDATE she’s almost done but is far enough along to drive i will add some pics
- shock towers still not in
- turnbuckles not in
And proline tires are in just not mounted

Just bought a circuit a few weeks ago. I think my servo sent. When the car is parked the tire stays turned to the left now. When I turn the remote it can turn both ways but it sets back to the left. You think its my Servo? or might have jumped a tooth? Either way I'm looking for a new servo. What are your recommendations? Thanks

So how many generations/versions of the Circuit are there (are the upgrades documented?)...as I was looking at a used one, but am now skeptical on what it's got inside?

if you put in the RPM servo saver eliminator bellcrank, and a metal gear servo, you will probably break your plastic servo arm.

I put a metal one in and its been solid
