I'm the opposite of @
Calum above. I think the fender gap sucks. It spoils the lines of a beautifully designed exterior. I think the stock suspension communicates well enough for DD street use and the occasional HDPE.
To me there were just a few minor problems with the OEM suspension that drove the decision to upgrade pretty quickly. Keep in mind, I wanted to keep the OEM springs/shocks, but couldn't find the product I wanted on the market.
1.
Wheel gap with the factory ride height.
Horrendous to the point that it was near impossible to just let it be. Otherwise, the OEM suspension was pretty ok. What I needed was -1" drop all the way around with something closer to -1.25" preferred. So I looked forever for was a way to drop the car on the stock suspension by changing the mounting points without installing shorter springs. After which I was hoping to correct the geometry and then all good.
The rear was achievable with lowering LCAs -20-40mm (W/ LCA products by Parts Shop MAX, and Stance) and/or top mounts from Raceseng and Robispec (at the time).
The fronts no luck. I could find lowering top mounts (HVT, Ground Control, and your Racecomp (out of stock) that would drop it -3/8" at most. But nothing more. Drop spindles might have worked but there are no parts on the market, and there still aren't. I thought about slightly shorter and stiffer front springs (-.5" to -.8") but then we get into suspension tuning including bump-stop/jounce bumper tuning very fast.
2. Improved highway ride
To start, really, I could have dealt with the stock suspension. So this is a secondary request. Anyhow, living in California it's pretty well known that the condition of our highways is quite bad. Highway ride on the stock suspension is generally compliant, but not enough over large bumps at speed. I hoped to specifically improve this with improved shock travel before the secondary spring/bump stop.
Notice I didn't mention "improve handling" or anything regarding raising the limits of the car because the stock suspension is capable enough on the street AND track for someone of my skill level. Also because I know that tires, pads and fluid would successfully raise the limits of the car when I was ready.
So, I started with springs, but those really didn't improve the ride so much as just chang it. From there I upgraded to my current RS*R Sports-i coils. An mid-priced decent quality coil that accomplished all the above without breaking the bank.
Still I'm waiting for some engineer/businessperson to put together a kit of decent quality components that use the stock springs/shocks but lowers the car a set amount between -1" to -1.25") for $600-$700ish (i.e. lowering top hats, LCAs, drop spindles, roll center correction, etc). If this is pie in the sky, I can accept that, but if not, it would likely be a first upgrade for most modders (even before a tune). The wheel gap is just that bad.
