Regarding spacers and their effects
So I might be using RSR down springs and spacers (based on peoples' results) 15mm back 20mm front. What will be effects of the spacers mostly? Will there be more vibration? Are they safe to use? I was thinking about using HR brand. Please let me know, thanks.

I have a pair of open-box Eibach 20mm for sale. Used to test fit then removed. I will sell those at 30% off.

Have had mine on for a week, no discernible difference. Just get good ones and torque them up correctly.

These are the ones's I purchased.
20mm spacer in front hubcentric
15mm spacer in back hubcentric

It's safe as long as they are hub-centric and properly installed. I have 20mm all around for about half a year and somehow the wider track lowered the car overtime(about an inch, compared with my friend's IS without spacers). Now my wheels fill the wheel well pretty good and I don't need to get RSR downs anymore.
Just a pic for how it looks:
Ignore my plate lol, was surprised that it wasn’t taken and got it as a souvenir. Sadly, ISFSPORT won’t fit. New ones are on their way.

Hey there, they are angled double wall tip (outer ones are shorter) and 4" OD for each tip if I remembered correctly. Indeed I do have Tsudo axlebacks, I basically told them to cut the original burnt tip off (all the way up to the muffler, no piping at all after the muffler now) and weld the tip onto the muffler. Worked out great. Just measure it first then try to get a shorter tip and you'll be fine.

Technically, the bore on a spacer does not have to be a precise fit. That would not be the inherent cause of vibration. The vibration comes from miscentering during installation. Which can occur from a bore mismatch, but not necessarily be caused by it. The bore being centered simply aids installation, particularly if you're in a rush or don't have good technique.
I used to be of that camp that repeated this until I actually studied what was actually going on. Lots of nuance in my statement so read it carefully.
But for all intents and purposes, try to get a spacer designed for your particular application.
As for the downside, you will experienced an effective reduction in spring rate. In other words, there will be higher torque on your suspension therefore you'll have a softer suspension. you'll also have increased wear on bearings. But nothing crazy so long as your spacers are reasonable.
Keep in mind more maintenance, more things to be aware of for safety, and more things to triple check. Your have doubled your surface area of contact faces and doubled your fasteners. Ensure you are purchasing grade 8 fasteners and ensure everything is torqued properly. you will also want to pull the wheels after a ride around the block to make sure your fasteners are still tight on the hub/rotor. Then wait two weeks and re-check.
you just have to be a lot more careful in general cause you've now introduced multiple dozens of question marks into the very things holding your car on the road.
