I have just bought a 1.4 Honda Civic EJ9 which came with a list of modifications. The plan was to buy one stock, then build myself but this one came up. £4.5k for a 118k mile EJ9 with:
-BC RACING COILOVERS
-EK9 REAR LIP, SPOILER, SPLITTER, GRIL
-SPARCO LIGHTWEIGHT WHEELS
-CUSTOM EXHAUST SYSTEM
-UPGRADED EXHAUST MANIFOLD
-TEGIWA UPGRADED RAD
-SILICON HOSES
-FRONT + REAR STRUT BRACES
-SILVER LOWER CONTROL ARMS
-SILVER SUBFRAME BRACE
-S200 STEERING WHEEL
-WEIGHT SHIFTER

This was everything I would've done myself. I wanted to build it myself as it would've been my starting point in modifying cars. Nothing major engine wise has been done so I still have that.
Anyway, the cat and car is too low. I'm thinking of raising the front by 20mm and the rear by 10-15mm to help not catching the cat on every single bump in the road, but I feel like it might not really be the height of the car, but the cat itself. It looks massive and very low. I haven't have the chance to get it on a lift to have a proper look just yet but I'm planning to by a smaller sports cat. Does anyone have any recommendations or general help to what I should or can do?
Thanks.

I also know it's on a curb, but that's the only way I can have a look. And can't get it on a drive so has to be parked there.
 
I have an aftermarket cat and its about the same size as yours. Your car is too low for UK roads. My coupe is at the minimum height to be legal and still has its exhaust snag on every bump.

Ah okay, just going to be a case of raising it and seeing what works and looks the best. Cheers
 
You could get bigger profile tyres to fill the arch gap, if the height you set it at looks silly.
 
Running 195/50R/15s at the moment, I’ll have a proper look and see what I can do once I get it on a lift.

The factory standard is 195/55/R15.
