How Off Road Buggies Should be Made! STi engined 320RWHP/TON! -Kyle's 2015 SRE Buggy Walkaround 

Thanks for the compliments, there is actually a second fire extinguisher in the passenger footwell, the one in the engine bay is more meant for minor fires and quick access, while the passenger one is for if it is getting out of control or if there is a fire in the cabin. Cheers!

The main reason a lot of off road buggies run the steering arms at the back is to try to keep the steering arms out of harms way in the event of impact to the front of the A arms, a damaged brake caliper is less of an issue than a buckled or broken steering arm.

Look at 1 million dollar trophy trucks where finishing the race and being strong is the #1 concern.

Chuck Kiesling I haven't done any videos on this, but if by styling you are referring to the design of all the boy panels than yes, styling will have a huge impact on downforce. If you styled the whole car so it was just one massive wing, it would cleasly produce a very large amount of downforce. Obviously most supercars etc are styled very similarly in overall shape, which is why wings, splitters and diffusers come into play more. However, anything that is in the airflow will affect the aerodynamics in one way or another.

Jonathan Nicholls I'll make this one a bit of a puzzle for you: It's to do with the aerodynamics kit, and works similarly to something that appeared in F1 a few years back which was subsequently banned... There are also a few other reasons it's high, such as giving more crumple zone in the case of a rollover and allowing the wing to be higher (rules define maximum aerodynamic device height from the roof level, not the ground level)

I think you should do a video on this puzzle. Looking forward to your video response.

Jonathan Nicholls It will have to wait for the aero kit to be finished first, I don't want to give too much away to the competition though!

That will be cool. No give-aways at all.

+Car Guy I'm not exactly sure what you mean by the first question, could you elaborate? Steering is rack and pinion, with electric power assist on the column from a Holden Barina.

KYLE.DRIVES like the pivot points

+Car Guy Yeah I thought you meant those, but do you mean the spaceframe structure joining them side side or the fibreglass panel between the mounts?

MrSkipturner Judging by the fact that you seem to race/track I Porsche I'm going to assume you know your stuff! The axles I'm running are 300M, and apparently good to 500hp in off road type vehicles. I'm limiting CV angle at 23 degrees maximum (apparently 930s are safe to 24 but some guys run theirs up to 27) and due to the double a-arm rear instead of trailing arm the plunge through the travel is very small (around an inch). Combine that with 27 inch axles and midboard hubs and it should be sweet right? Anything I'm missing from your experience?

+KYLE.DRIVES When I said axels, specifically I meant CV's. Like all things, the potential problem is relative. How you drive it(I assume you built it to thrash it), terrain you are on, application of power under full suspension load, weight of the off-road tires, etc., etc. With Porsches at the track almost every serious racer I know has upgraded axels(b/c we have replaced many on site). We also started with an OEM upgrade(like 930 axels), but found that they fail too. Lots of power and lots of grip is hard on joints, especially an articulating one. We have a saying, that you should like, every time one fails; "you can't beat physics". I assume you plan to keep the wheels spinning, but application of the power, say after a hard landing could be where you have a problem. Paved tracks are relatively new to me, but after 26 years of off-road driving, there is definitely one constant; you have to assume Murphy's Law. Good luck, I look forward to seeing it in action.

since your running with a arms you can buy none plung outter 930 cv's that can go to 44 degrees and inner's that do 40 with a slip shaft!

pretty sure hes an aussie man

+Eshrekticism Normally, yes, but the rear weight bias on this car is significant and the grip levels are not, so weight transfer is minimal, hence the brake bias is pretty even. The reason it has bigger rear brakes is because I could get those 6 pots bundled with the axles for a very cheap price, if price was no object I'd probably have used the same calipers all round.

KYLE.DRIVES Ohhh ok. Thanks for the info

MyLonewolf25 no they are not pal

Kyle McGillivray seeing as literally 90+% of the world is left hand drive Yes it is The only reason we ever drove on the left side of the road dates back to horse and kart because we had swords That's it We then moved to driving to the right hand side because of the invention of firearms made swords nearly obsolete and favored driving on the right hand side Also driving on the right hand side is MORE efficient than left And depending on which side you're driving on determines what side you want to drive on Now to fight for motor sport reason Because of how most motors are setup it favors the driver being on the left of the vehicle for steering rack placement and packaging of the motor Quite frankly the greatest placement is the driver in the center but that's a whoooole nother can of worms

MyLonewolf25 fair enough with the conclusion
