What mods did you find overrated and underrated?

Bought CS spoiler, diffuser, rear lower splitters, front upper splitters, and their mirror caps. All have good heft to them, not that cheap flimsy plastic with carbon just laid on top that I had with some eBay bs.

They all have great fit/feel/fitment for the price, except the CS spoiler (the ends don't sit flush, I did install it in the winter so it may have not been as malleable to have it sit properly, but it's held up with tape over 110mph).

I wouldn't hesitate to buy from them again with 100% confidence. Shipping/clearing customs can be slow so be patient.

Be well!

Agreed; cheaper solution is using rubbing alcohol to remove the US airbag warning labels!

SSR intake underrated.

Added windshield tinting to my appointment thanks to this thread. I've always gotten mine done on my past cars, was worried how it would show for cars with HUDs. Happy to know that polarized lenses will work!

Overrated: Any carbon fiber piece that goes on top of parts of the car. Seat backs, center armrest cover, on the front bumper (not the bottom or rear spoiler but everything else)... these mods suggest lightness by the use of carbon fiber but unequivocally add weight as they don't replace the part. Bizarre lol

Underrated: 513M wheels and factory charge pipes. Those wheels are about as light as anything else on the market and can fit the same size rubber as is on the ZCP. And as for the charge pipes... they can handle quite a lot more than they're given credit for and it's a waste to swap them out prior to having an issue.

Interesting… that does look nice

Underrated: Removing the carbon filters in the air boxes and running high flow performance filters in it. Really changes the sound and you can feel the difference in throttle response for sure. After market intakes look cool but they don't really add any power, the stock intakes are very well designed.

Any recs on where/what brand to get for the high flow performance filters? How often do you change them? Thanks

Amazon has a decent price on BMC drop-ins:

BMC's recommendation for maintenance:

While you're installing them, remove the charcoal filters in the lid of the filter housing.

There are a lot of companies that have them. KN, BMS, eventuri, AFe, im sure others as well. Check them as often as you want. Clean them as often as you want.

One more questions regarding intake. What you are saying it's better to invest in BMC or K&N drop-in high flow filter and its as effective as ait intake system like BMS elite performance intake?

i'm undecided either shall i buy K&N / BMC or invest in BMS performance intake

BMC > K&N > BMS.

BMS is known to create idling problems due to the maf sensor placement.

Just to be sure We are talking about these ones?

Yup but you can find the same on Amazon for about $105.

This is the review that I didn't get these filters. The oil can sometimes cause maf issues. Also hate the whole cleaning process. So you take the filter out which is a pain in the ass anyways and now you gotta wait a day to clean and replace while all your screws are out. Makes so sense. Would have bought one if the oil issues didn't scare me.

Out of the box, the BMC filters are very lightly oiled. The reviewers must have cleaned and over oiled them, which is easy to do.

if cleaning is the case , you can always purchase two filters which is still cheaper more than 50% from performance intake and have separate one always ready as a replacement

In case of air flow, is it the same gain using BMC as using performance intake system i.e VRSF?



PS: The price has dropped. 279$ seems interesting now.

Air flow and performance may actually be better with OEM with BMC filters since OEM is considered a cold air intake drawing air from the front of the car. VRSF and some others are drawing hot air from the engine bay.

Stock intakes are not a bottleneck with these cars. It's already very well designed.

thanks hellokitty ! So i'm ordering BMC now

With the charcoal filters removed, is there really any performance gain with the BMC filters over clean, new OEM paper filters? I can’t imagine you can achieve any more air flow
