C63 507 $6-7k to spend on mods, suggestions?
So far I have got a secondary cat delete replaced with stainless straights, ROW box, and an OE stage 1 tune.
It’s been a good year and I’ve got some extra cash to play with, so if you were in my position, what would you spend 6-7k on?
I am thinking of ARH long tubes + x pipe, which is almost 4K of my budget with the install. Besides that I’m thinking of after market diffuser, spoiler, lip, and maybe a sight tint on the tail lights paired with a chrome delete. I am keeping this car forever to give to my future son, so I don’t care about resale value.
Thanks guys, appreciate any input
I think I’m going to do headers for sure and yeah I’m looking to drop 1-1.5 inches but I’m honestly not too familiar with suspensions and lowering cars. Do I need anything besides HR springs if I were to get them, like spacers all around or would I have no issues and rubbing stock?
Is this also a doable job for around 1k if I go with springs?
Thanks again

my thoughts if you don't go with a blower...
- Headers are solid gains for the $ spent....
- Eibach bars if still avail along with ultra racing fornt /rear tie bars sorted my ride so that I don't want to lower it now.....
- you look to be in Cold climes so E85 might not be an option - but the gains per $ are amazing if you have access to Ethanol and can live with a cold blooded beast...
- Billet Pulleys are good PM and offer some gain if you do the Underdrive main ( and do the tensioner while in therefor complete PM)
- LSD if yours didn't come with it.... my next mod.
- Wrap the chrome - easily done for 300-400 by a good shop - on a black car it'll really transform the look. Carbon fiber I'd think less so - so maybe save that $$
right on budget.
right on budget.
im gonna guess most people are FBO over supercharged because they modify over time, instead of dropping 7-8k at once. Right now this is a damn hard choice to make.




Then when you're done you can take off and sell it for at least $4k back
yooo that is right on the money there. Man I came from a C300 with 228 HP, to a 500 HP C63 and now possibly 700+ with a blower... the power progression is crazy haha I don’t know if I can handle it, sometimes my current mods have me scared. 😂😂

But if the power is not enough for you and you want more then get a blower and you will never regret it.
