Hey there, Oliver!
Great question about struts/shocks selection for your Sonata - with how many options there are on the market, it's always a good idea to be selective and make sure you find the right one. Here's a breakdown of your options:
- KYB: Known for high quality, often recommended for its longevity and performance. A bit pricier, but they can be a worthwhile investment, especially if you seek a balance between cost and quality.
- Monroe: A budget-friendly choice. Some users report satisfactory performance, but others have encountered issues like internal faults leading to noises. It's an option if you're looking to save costs and not aiming for top-tier performance.
- FCS & TRQ: Less prominent than KYB or Monroe, but can be viable budget options. Quality can be hit or miss, so they're suitable if you're prioritizing cost over longevity or performance.
Regarding your side question on rear coils, it's generally advisable to replace them if they show signs of wear or if you're aiming for a comprehensive overhaul. However, if they're in good condition and you plan to sell the car soon, you might opt to leave them as is.
In summary, if you're looking for a balance between cost and quality, KYB seems to be a favored choice. If budget is your main concern, Monroe, FCS, or TRQ could suffice. Remember, you often get what you pay for in auto parts.
