looks like ill have to bite the bullet on these and right a review.

3.16k front spring rate is very very soft (177 lbs/in). There will be a lot of dip on the outside front corner.

The WL roll center kit will help, but that's still a very soft spring.

Thanks! the rest of that stuff I can figure out on my own.

Right on! Looking forward to what you have to say.

I just got Vorshlag plates in and i wanna know if i need to take off the coilovers or can i just take off the 3 nuts holding the coil to the shock tower and just slide it on then fasten it down? Thanks

This is hard for anyone to do. It all depends on what your goals are. With the suspension points measured one can relate ride height to a percent spring rate increase to maintain the _____ front roll stiffness (fill in ____ with stock, softer, stiffer) and same for rear. Then do the same thing but also take into account playing with the roll center height for different spring rates. This method would analyze this using the kinematic roll center which is useful but not as accurate as it would be with the force based roll center.

In the end it comes down to personal preference and what balance you're most comfortable with (neutral, oversteer, understeer). Without having a full tire model it would be more of a roll stiffness distribution value, instead of an actual balance value.

Also keep in mind that playing with toe and camber can have a HUGE affect on your vehicle balance in corners.

Oh so many factors

You'll probably want to take the coilover completely off the car.

yeah, it was kind of an impulse buy because i found them on sale.
I thought id give it a shot. theyre not as bad as i thought, but maybe its because i havnt felt something better. we'll see how this does i suppose.

Tag me in a post with @CSG Mike if you need a response; I can't watch the whole forum

I'm not 100% sold on the control arm bushings but don't want to spend the money on proper lower control arms right now.

Slotting the front struts seems like a perfectly viable option. Some cars(used to anyways) come straight off the assembly line with this exact setup. The price is right and I would think this is where you would want the adjustment to be made. Is there an advantage to adjusting at the top of the strut? Loosing a rubber upper strut mount seems like a disadvantage as well.

You're playing with the angle of the damper when you do that... smaller angles don't have too much of a negative effect, but there's limits to the angle..

Question, I've really tried to wrap my head around spending $3k+ on coilovers but I just can't afford it. I would like to run coilovers for their adjustability, allows for more room when running certain wheels, height adjustment. Most in my price range 1-$1600, are single adjust either rebound or rebound/compression and i opt for swift springs as I understand they're much better than springs that come with coils at this price range. If you had to choose between the fortune autos, feal, BC... What would you recommend. I do mostly steer driving and maybe once a month HPDE. Thanks.

Are they really that much better than FA, real..They're on the top range of my budget and don't even have top hats or adjustability to damping. I don't mind because i could always use the factory and adjust camber with bolts. Camber plates would should the price over the 2k with these.
