Dear @Pranjal Varsani with my Nissan Patrol Y62 (2020 model) I went through the following learning curve:
1. I damaged both front and rear bumpers on my very first drives off-road (after just 2-3 drives, at Newbie Level), then:
- Changed the front bumper from "City" to "Offroad" stock version (Nissan said it couldn't be done, but with some fighting I got it installed)
- Installed a Front Skid Plate (8mm straight and stiffened with two double ribs) + 35mm steel rod behind bumper for protection for frontal impacts;
- Installed a Rear Skid Plate (4mm, rounded) to protect rear bumper from being ripped apart by sand scooping in the central part.
If you go for skid plates make sure there is adequate space between plate and bumper to allow for elastic deformations in case of impact, otherwise they serve little purpose (I asked for 20mm min).
2. After approx 30 drives (having reached Intermediate level) I damaged my front bumper again, despite the skid plate, due to an impact from the side while attacking a dune from the slip side, then:
- had the front bumper replaced and cut by approx 13 cm and installed a 35mm steel rod below the cut line with welded lower metal plates closing the gap left by cutting the bumper at sides of the skid plate (to minimize sand intake) for protection for angled / lateral impacts
3. After approx 50 drives (having reached Advance level) I damaged again the rear bumper again despite the skid plate (bent it outward from the side during a forward tug due to sand accumulation between the rear wheels and the mudguards, which were stuck in the sand with heavily digged in wheels and held the bumper back while the car was being pulled from the front), then:
- removed the rear mudguards
I am yet to replace the back bumper (currently held in place with gorilla tape), as I am waiting to see if with no mudguards I still have issues and need to cut the rear bumper as well or not (which looks horrible as you end up seeing the whole exhaust pipe and the spare wheel).
It must be said I'm a bit fixated with maintaining as much as possible the original aesthetics and doing always the less invasive and less visible changes, as the car is still meant to be driven on-road mos to fhte time.. I therefore hate the idea of installing proper aluminum or steel off road bumpers. They are bulky and squared, and I don't like the aesthetics (personal taste), so I prefer to keep stock bumpers and have them cut and modified in a smart and less evident way.
All work done at Bahwan Motors, even if I suspect in the end the job may have been done by the usual guy in Sharjah. I must say I have put a lot of effort myself (and shown my most annoying attitude as an engineer by mindset and education) in the design and execution of all changes, otherwise aestethics would have been totally compromised and (skid place were redone 3 times each before the guy could get them right l)..
I learned by my own mistakes and damaged and progressively understood what I needed. A bit annoying, but quite instructive. I have mentioned the number of drives above so you could realize you don't need to do everything at once..
I'll share some photos tomorrow.
