Thanks

The Whiteline rear camber bushing is the less expensive part and it works well...it's just a real pain to install and should be performed by a very good shop.

Rear lower control arms are more expensive, but easier (or cheaper) to install and adjust.

You really can go either way. I personally believe the bushing is the better place to adjust camber but it's not a huge deal.

Your alignment does change slightly when you raise/lower the car. It does not change with new wheels.

Was planning on just going with RCE Yellow springs but this Tarmac 0 option looks interesting. If my goal was a high performance dd that could provide the final cure for any porsche envy I may still have, would this offer tangible advantages over a Yellow springs & Koni combination? I know coil overs leave more room for larger wheels/tires, and allow for deeper drops, but if I am focused on the "go" and not concerned with the "show"....does it make sense to just go straight for the Tarmac 0 when the time comes?

Thanks,

Greg

Both set ups are very good for a "sport plus" type of guy that DDs their car and wants a little extra fun with a good ride. You don't "need" to drop the car a lot with the Tarmac 0s and with a mild/medium drop I would say the ride is slightly better since you'll have a hair more travel and softer front spring rates. You can get the Yellows + Konis out the door for a little cheaper though.

do you provide optimal alignment when buying coils from you?

Let's say I'm getting yellow springs. How do I know which one is a perfect alignment? Is there any recommended spec?

I just bought the tarmac O and Myles gave me detailed alignment specs based on my intended use and the adjustable bushings I was putting in, so to answer your question, yes.

One of the many reasons to buy from RCE, knowledgeable product support.

so when I get coils. Do I still need adjustable bushings? Does it come together with the package? I feel so noob lol :S

I just want get a nice ride with a nice drop. Should I go yellow instead?

Yellows are 20mm drop, static. Tarmac Zeros are height-adjustable. Combined with the fact that the forces of the Zero are not adjustable and you don't mention interest in adjusting forces, the Zeros are probably the better choice for you. Also the Koni warranty process is some shit, but that's bad feelings on my part.

With a threaded-body/height-adjustable coilover you change camber as a side effect of lowering the car, which is incorrect. This is fixed by using an adjustable length lower control arm, which is also the incorrect way to adjust camber (as this arm changes toe angle AND camber angle with one adjustment). The Whiteline camber bushing adjusts the UCA position, which is the correct way since it doesn't alter toe. Bushing cost + labor on the install will cost you more than a LCA + labor (you can install the LCA in your garage when you do the coilovers, too!).

Since your yellows have the same spring rate front and rear, why did you choose to ship the Tarmac 0 with staggered rates?

[BRZ NA]

Really wondering what's the different between kW set up?and which one is better?

[hanabie]

@RCE, does rce yellow springs come with alignment specs?
thanks

Are you referring to the Tarmac ZERO?

It was a middle ground set up option since the standard rates are 225/280. Knowing how easy it is to add front springs, I felt it was best to make the square set up as an option. Its easier to add 280 front springs later. We have a massive amount of 280 front springs on our shelf. But this is something I do in conversation during the sale on a case by case basis. If it proves to be that everyone wants 280/280 square then we may make it so our kit comes with 280/280 square. We will cross that bridge when we get there.

The other reason is when you start making the rear of this car firmer on a set of shocks that is NOT damping adjustable you must make some sacrifices so that its not TOO firm in the rear so we made sure with KW that compression damping was forgiving in the rear in the areas that could make things uncomfortable. But having a good rear rate was absolutely necessary. hence the 280 lb rear spring. Similar approach the stock rear shocks have BUT....with more damping force.

Lets put it this way if someone wanted to run 400/400 on these shocks they could easily and it would NOT be underdamped.

Again this was about..."options" that could be had on a damper without a knob.

ps: sorry for the long answer.

Our sister company GTWORX started working with BILSTEIN USA back in early 2009 to develop a oem fitment option for the 08+ WRX which had ZERO shock options. So this isnt a "new" thing for GTWORX to co-brand with BILSTEIN on the fixed perch style strut/shock option.

So yes we establish the type of valving we want and for what range of spring rates and the drop. We work directly with the engineers at Bilstein west to find the best profile for our needs. This is done over a period of 2 weeks on Socal roads. We then take a sample set back to the east coast and put roughly 2-3000 east coast , horrible road miles on the prototypes. Its then signed off on and approved for production. Prior to that we normally try about 20 different valvings.

Hope that help understand the process.

Keep in mind that option from GTWORX is 6 months out at a minimum.

As long as I know it's in the pipeline, I'm happy to wait. My Yellow's and stockers are doing great for now.

Wonder what I could sell Konis and Yellows for...

How much for Tarmac Zeros with 280 even rates Andy/Myles?
