Thanks Jahanzeb bhai, yeah like I said previously, the current placement of the filter was just temporary as the pipe was sitting there without any filter and could have catched dust and what not, something was better than nothing for the time being. I'll mount the battery like it sits in the EF Civic engine bay, that way I'll have more room for the filter to sit behind the headlight rather than right in front of the radiator.
Coilovers are definitely stiffer than the stock assembly, handling has improved a LOT since there was tons of body roll previously and now it's close to none, sticks to the tarmac no matter what, but they're comfortable for a daily driver, I've never been a fan of soft suspension anyways. Will adjust the coilovers properly once the car is back from the workshop, raised them so that workers won't scrape the car while moving it from once place to another.
