Stocks Suspension - mt wellington. all they need is the outer diameter of your front strut housings, so they can give you a slide on sleeve that fits perfectly. once it slides on it is secured with 3 grub screws that clamp it onto the strut housing

then you can use any coilover spring you want (of the appropriate diameter, usually 80mm springs) in combination with the sleeves.
as for the exhaust angles, yeah not saying anything is wrong with it, but my car had the tips angled up about 55degrees from horizontal, tucked as close to the body and bumper as possible, and ending around bumper height. so only one join was necessary, since the tips werent too long, they didnt protrude back too far. JArrods here is angled almost 80degrees directly upward, so to go straight up like that you end up with this straight pipe out from under the car then a sudden 90 kick up, which to me looks weird, because i dont think ive ever seen any boso pipes exit the vehicles at 80/90degrees up - they all angle up between 50-70degrees at the most.
if jarrod angled the pipe at the current length to 50 degrees, the tip would end up probaby 2 foot behind the rear bumper line, it would make the whole car 2ft longer, and wouldnt be allowed on the street at all. we are talking about balancing this "look" with actual usability on NZ roads - of course if you wanted to model a boso exhaust exactly like in japan, you would be prosecuted immediately here. so im not talking about copying the look exctly as well because thats a moot argument
you might think its pedantic arguing degrees of angle but it isnt, its all the visual perspective of the look and one wrong angle makes the whole thing look different
it took me 3 tries to get the angle right, and it was only achieved by visually mocking it up a hundred times before final welding
anyway not trying to tell u what to do, i was just trying to explain the reason and physics behind why something might look "arse" or not, because it all comes down to natural visual flow of lines and angles, lengths and breadths. its all a abalance and if you upset one point then everything else loses its flow, so when the eye casts over it, you dont need to have a trained eye for your brain to realise if something seems "off"
