One last question for you Andrew,

Are RCE yellow springs linear , or progressive? I thought I read somewhere they are linear F/R. Just comparing them against TRD springs, then I can put this puppy to bed.

Thanks in advance.

They are as linear as possible. There is a slight progressive portion that is basically closed at normal ride height but there so that the so springs aren't too short (similar to a tender spring on a coilover).

Tire choice is the #1 variable to consider. Like others have mentioned, putting a very sticky tire on the car really changes the character of the car. I won't say better or worse, but it's different. Obviously for some more absolute grip is the goal but if you're not chasing lap times, more grip might = less fun. The car will of course have higher cornering limits even with stock suspension, but it will feel a little sloppy due to excessive roll and movement. A sticky tire will make the car want stiffer springs, which will require firmer dampers, and if you want firmer dampers that don't beat you up you have to spend some real money. On top of that you'll want to start thinking about replacing OEM bushings with something firmer since the flex from OEM bushings will be more apparent and you might add camber plates for more aggressive alignment to take advantage of the grippier tires and....I think you get the idea of the rabbit hole.

For a street car, a tire that has consistent and reasonable grip is the ticket IMO. Michelin Pilot Super Sports are a popular choice for a good reason.

If I were building a fun, reliable, reasonably fast, simple and budget friendly BRZ/FRS suspension tomorrow (and I do think about this all the time), I would do:

1. RCE Yellow springs
2. Bilstein B6 dampers
3. camber bolts and rear LCAs with good alignment (-2 deg camber front, -1.8 rear, 0 toe front, tiny bit of rear toe in)

After that, I would consider RCE front and rear RCE swaybars OR just a take off OEM 16mm rear bar. Or keep bars stock. Also maybe a few key bushings (especially if you got some mileage on your car).

This handles and rides very well, will last a long itme, and be FUN.

I do mostly like the Bilstein B14, but I don't like the soft progressive springs very much. It's a good quality damper though, which is why I generally prefer Bilstein over some other options.

The Bilstein B6 dampers are actually a great match to our RCE Yellow springs (and for that matter a handful of other springs out there as well). We've tested them together and examined shock dyno...it's a good quality shock and better than what's in many coilovers. I don't recommend any spring that lowers more than an inch. Our RCE Yellows are a mild/medium drop with carefully chosen spring rates and include replacement bumpstops so you get back some of the travel you get from the mild drop.

A lot of people assume coilover = better but that is not always the case.

Sorry for bring back such an old thread but I was wondering if this set up you mentioned would be able to fit 9 inch or 9.5 inch wide wheels? Or will I need coils for them?
