JB74 3-Door — Lightweight OEM+ Build Feedback wanted

Hi all, I’m setting up a new MY26 Suzuki Jimny JB74 3-door in Bluish Black Pearl and would really appreciate feedback from people with real-world Jimny experience.
The goal is not to build a hardcore crawler, show car, or heavy GVM-style tourer. I’m aiming for a balanced, lightweight, reliable OEM+ build for:

• mountains / alpine driving

• rural property and farm use

• mild off-road touring

• regular towing of a lightweight companion trailer

• long-term durability and daily usability

Weight discipline is a big part of the build. I’m trying to avoid unnecessary mass, especially on the roof and ahead of the front axle, while still making the vehicle properly useful.CURRENT JIMNY BUILD DIRECTIONSUSPENSION / GEOMETRY

• High-mounted filtered manifold in engine bay

• • front diff
  • rear diff
  • transfer case

SIDE PROTECTION

• Horntools aluminium tube rock sliders

FORWARD LIGHTING

• STEDI ST3K 21.5-inch slim light bar

• To work with VIKOR integrated VKX cube lights

COMPANION TRAILER CONTEXT
The Jimny is also being set up to tow a lightweight custom companion trailer, so the towing setup is being designed as a vehicle/trailer system rather than as isolated accessories.
The trailer brief is:

• lightweight single-axle utility trailer, not a camper trailer

• builder-recommended ATM, likely around 750–1000 kg

• typical real use around empty to 300–650 kg loaded

• loaded towball target around 50–70 kg

• electric brakes via Redarc Tow-Pro Elite V3

• Cruisemaster DO35 coupling from initial build

• low tare and stable towing prioritised over maximum payload

• no fixed trailer battery, solar, inverter, fridge system or heavy toolbox

• no dedicated trailer spare if the Jimny spare can be used safely/legally as emergency spare

• used for rural property work, compact ride-on/zero-turn mower transport, firewood/general loads and mild touring support

• low-profile tailgate plus removable lightweight ramps for mower loading

• ramps to normally be stored off the trailer unless needed

• designed around rear-door/spare-wheel clearance, X-Bar clearance and safe handbrake/jockey-wheel placement

I’m deliberately trying to keep the trailer light and disciplined so the Jimny isn’t being asked to tow a mini expedition trailer.FEEDBACK WANTED
I’d especially appreciate feedback on:

• OME spring choice with this lighter front-end philosophy

• towing behaviour with X-Bar, Tow-Pro and a lightweight braked trailer

• whether a 50–70 kg loaded trailer towball target sounds realistic behind a modified JB74

• real-world experience with X-Bar + DO35-compatible hitch geometry

• VIKOR / Carbon winch direction versus heavier traditional bar/winch setups

• Invicta hybrid starter batteries in Jimnys

• roof rack and roof lighting wiring routes without drilling

• using the Jimny spare as an emergency trailer spare

• whether damped lightweight trailers behave noticeably better behind short-wheelbase 4WDs

• anything that looks overbuilt, underbuilt or likely to cause fitment headaches

Overall aim: a lightweight, reliable, useful Jimny — not a max-accessory build.

I'm going to go out on a limb and suggest this is not a uk build, mainly because of the bull bar. Consequently I can't really offer specific product experience. However I like the idea of keeping the weight down and have looked in the past at lithium starting at the time there were concerns about the heat resistance for lithium batteries in engine bays however I accept that the technology has come on leaps. As for general towing I regularly tow at full 1300kg capacity both materials and livestock and my 2024 is quite capable as long as you accept it really doesn't like hills going up as it's not very powerful and going down it's not very heavy, but drive accordingly and it's fine.

I'm not familiar with all of the bits, I'm also in the UK. But by and large the list all looks reasonable.

What I would say is, if you plan to off road the Jimny has a couple of weak areas. Firstly in ground clearance and secondly in suspension travel. They are both pretty limited in stock form.

The OME kit is meant to be high quality and I suspect it will ride and handle very well on road and probably on tracks too. But the lift is minimal and it won't really give you any improved articulation. So its benefits to off road performance are limited beyond the improved damping.

I fitted the Black Raptor Premium 2" kit to my Jimny, I think you can get this in Oz.I was very impressed with it. A proper 2" lift that increased the suspension articulation, giving a much more stable vehicle off road. The shocks are also top quality and adjustable, which might be handy if you are towing, as you'll be able to tweak them to the conditions and weight and readjust later when not towing.

IMO with the 2" kit it handled and rode better everywhere over a standard vehicle; on road, off road etc. And was a more capable machine because of it.

As ground clearance is an issue I'd also recommend some under vehicle protection such as a skid plate for the transfer box and radius arm mounts. They are very easy to impact and get hung up on.

Lastly tyre size. I had 215/75R15's on mine too. And they were fine. But later on I switched to 235/75R15 and they were much better IMO. I wish I'd gone for that size originally. With a lift and non factory bumper they should fit fine. If you are an auto it might impact performance a bit, mine was a 5 speed manual and I couldn't really tell much difference if I'm being perfectly honest.
