Hi i own a mazda 6 just finish loan like last month. The first thing i did give a fresh paint looks good now. Planning to mod my car. I am not sure where to start for the mod. I am not trying to race or change to car to track mode. I am more focused on modding to make the car more enjoyable.
The list of plans i have now :-
1. Get the car noise proofing treatment ( Cannot tahan )
2. Change brake kit ( Wan good stopping power )
3. Better suspension ( I want more comfort )
4. Limited slip differential ( Need do more research)
5. Add more power ( Need do more research)
I did some research found this shop called autofoam kl which quoted me sound proofing pissed package for 4k myr.
Looking for a good 4 pot regardless brand as long have some decent reputation. Budget around 4k myr.
Is there any other shop u guys know do sound proofing. 4k is pretty steep. Probably other shop offer same customization for for cheaper price.
Time to upgrade
If you want more comfort, instead of fiddling with the stock suspension (which normally is already the best setup for comfort) you should just downsize from your 19' rims to 18'. This will make a noticeable improvement in comfort as you'll get more cushioning from the thicker profile tires. Change to 18' but wider so that would improve comfort AND also allows you to use wider tires which will improve your handling too while looking more aggressive due to having wider footprint. Downsizing to good lightweight 18' also enables you to save some weight which help your acceleration and FC just a bit. Anyway anything that saves weight is always a positive.
As for mod for suspension, they're all mostly for more sporty handling and looks, not really for more comfort.
Also no need LSD if your focus is just to make it more comfortable instead of more aggressive car.
As for adding more power, NA engines lie your Mazda is not easy to get more power even after spending a lot of money. Most often just do some remapping and intake-exhaust mods but at most it will just give like 5-7% gain at best, so don't expect much out of simple mods on NA engines. Not sure though which tuners have good experience/knowledge to do good remap for Mazda Skyactive engines.
For your first 2 mods on your list, they're good to do especially no.2.
