I tried searching for mods and defects topics and such on the forum but it's only briefly mentioned every now and then (from what i can find).
I skimmed through the RTA car safety whatever PDF's and it seems like basically most mods you see around like coilovers and wider wheels seems to be "defect" worthy but you can get engineers certificates?
Where would i be able to get one for whatever mods i've done/will do? Does it cost anything? And is it possible to find some lenient ones hahah??
I just want it just in case, and less worry about cops. Don't get me wrong i think cops are tops but here's an example of a mate's mate that got a defect (crops for identity purposes (hopefully) hahah)
He drives an NA facelift gen 2 impreza RS (sorry i dont know the term)

- Fair enough his horn wasn't working and im not sure what "pipe work on engine is" (i assume intake)
- His car was probably loud "aftermarket exhaust system" but the cop didn't even know why it was loud (he didn't get done in for not having a cat).
- But a rear tow hook was apparently only for track use.
- "Non standard rims and tyres" but he actually only had the STI enkeis on ..
- and "suspension bar" was actually just the front strut brace .. and the cop's excuse for the last 2 items was because they didn't come standard in the car?
- He also didnt get done in for a massive sticker across the top of this windscreen (which i think is meant to be defect)
And of course comments about people getting done in for HID's.
So being new to the modifying game i got pretty damn confused. I thought most of this was fine and all i had to worry about was not being too low, no poke or stretch and quiet exhaust? or should we get it certified anyway? which brings me back to does it cost anything LOL? Do the turbo guys have to get all their supporting mods checked out?
ps. im now second guessing if this thread should be in this section
