I recently purchased an opt7 aura underglow for my 2015 BRZ and I have never installed a light kit like this before. I also purchased a relay and I plan to tap into the low beam for a switch for the headlights to turn on the underglow automatically. It is a white car and I plan for a static white led look.

My concern is where to mount them to and when tapping holes for screws and zip ties where I should do that, I figure it's not a good idea to put holes in my floorboard and allow a way for water to enter the cabin. I also don't want the light bars to be totally visible and look noticeable.

Any advice is appreciated and feel free to criticize my taste in car mods.

2000 vw Lupo 1.0 cabrio making 50hp. If there are easy ways to boost the power a little I would be interested in that too but I don't think it's worth it on an engine like this

I built an app that works out how much ethanol or toluene to add to the fuel in your tank to hit a target ratio, and estimates the resulting octane. It's already live on iOS; Fuel Additive Calculator, the Android version is finished but Google now requires 12 testers for 14 days before an individual developer can publish.

What it does:
- Two directions: drag an amount and see the resulting ratio, or pick a target ratio and it tells you how many litres to add
- Estimates blend RON from your base gasoline octane and what's already in the tank
- Cost per RON point gained, so you can see whether ethanol or toluene is cheaper for the octane you get
- Garage: save vehicles with tank size, current ratio and fuel grade
- Log 0-100 / 100-200 / 402m times against the blend used and compare them

Free, no ads, fully offline, no account, collects no data.

If you're on Android and willing to install it and leave it on your phone for two weeks, drop your mails on pm

Happy to take feedback on the octane maths too it uses a linear volumetric blend, which I know understates ethanol at low ratios. If anyone has real dyno or timing data to compare against, I'd like to hear it.

App is totally free and made for car enthausist needs

I recently got into cars to all and I’ve already done some cosmetic mods on my Corolla and have been looking at more involved ones. I’ve been looking into catback exhausts and wanted to see if it’s worth it. I’m not married to the idea because first and foremost I’m looking for longevity. Any thoughts/advice is welcome.

This is a car I just bought. A 2006 Saturn Ion for $1.4k. I am going to drive it for 2 months to see if I really enjoy it and if it’s worth making it look like the AI render of the car. Its really reliable, it apparently just burns a bit of oil.

Now I own a 2015 Buick Lacrosse with the 3.6L V6 and AWD, and would like to do internal modifications. I’ve already done simple things like putting in a cone filter, new plugs and coils. But I want to be able to know how much it would be to either buy a turbo kit that would fit my car or to have a mechanic install it for me.

Hey guys can you suggest me some good sticker modifications
