Default few Questions about brakes,exhaust,springs

Just got a couple questions about a few things. I just got some 20" rims for the summer and when I had them on for a few days the brake dust from the dealer installed pads was annoying. Which pads have the least amount of brake dust? Im planning on getting the Raybesto rotors and their high performance pads anyone try those?

After I deleted the resonator from the exhaust I get a raspy sound when I rev it and I HATE it. Would getting new mufflers and tips solve this? Which mufflers would be quite but have a nice rumble? My main objective is to get rid of that raspy sound because I have the cutout to be loud. Anyone know where I can find OEM looking tips without that stupid baffle in the middle?

Im definitely going to lower the car in the summer but how low can i go with the 20s? I think Canuks has 2 different heights a 2.1 front and 1.7 rear or the 1.7 all around. I would like to get the 2.1 in the front and the 1.7 in the rear because how the rear tends to "sag". What else would i have to get in order to have 0 problems with the alignment and tire wear.

And lastly should I tint the LED taillights? I tinted the stockers and loved the look but these taillights look a lot better then the stockers. ill upload some pics when i get home.

im pretty sure sure that ceramic pads cause less brake dust but that's just from me trying out different pads. about the exhaust ill be honest idk you probably need mufflers and i say spray the tails lol. good luck though mang

The springs are a 2.5/1.5 and a 1.7/1.7 I would recommend you get 8 camber bolts to maximize the adjustability when you get an alignment. As far as the tails I'm also debating on getting them tinted. For the raspy exhaust just throw your res. back in and call it a day

To get more adjustment for the alignment you'll need 8. I am using 8 and I'm right at spec on my alignment. Thats the only reason I said to use 8. I don't know if it is the drop being so low or what it is

When i had just flowmasters 40s there was alot of drone especially in 4cyl. Lots of rasp while accelerating. I put the resonator back on and now it just has a deep grumble without all the rasp.

No, 4, lol. The ACDelcos provide greater adjustability than the Moogs.

I am currently dropped 2.5"/1.5" with four (4) camber bolts in the upper bolt holes (one per strut). There's no need to waste money.

My car is always within specification when I get alignments (unlimited alignments here with Firestone).

ACDELCO Part # 45K18036. RockAuto has them for ~$13 each.

As for the unlimited alignment, I got mine for just over $100.

If you are just worried about the rasp when revving you can tune that out. The ECM pulls spark to control RPM, leading combustion to not finish by the time the exhaust valve opens. Upping spark will make the engine hang a bit more, but there is a sweet spot.

Ceramic pads generate less dust than the stock semi-metallic pads, and it is lighter, but you'll be giving some pedal feel and stopping performance (especially when the pads are cold).

thanks guys
I REALLY want to do the 2.5" 1.5" drop but im worried about rubbing. The OD of the 20s with tires is less then the OD with the Alcoas and tires so i shouldn't have a problem right?
