ASK ABOUT NEW RCE
SWAY BARS FOR STI

Default Gauging Interest 2015+ Gtworx/Bilstein Sport Shocks

Racecomp Engineering and GTWORX have been hard at work developing a new GTWORX Bilstein Sport fixed perch damper specifically for 2015+ Subaru WRX and STI (VA chassis).

The GTWORX Bilstein Cup Sport kit has proven itself with previous Impreza and Legacy applications as an OEM fitment damper tuned to provide coilover level performance. The next generation WRX and STI will receive the same treatment and allow those with Racecomp Engineering Yellow springs or OEM springs to improve their vehicle's suspension system with the quality of a custom dampers from Bilstein, a world leader in monotube gas pressure shock absorbers and GTWORX, a suspension innovator for Subaru performance enthusiasts.

Stay tuned for more details!

Release date: February/March 2016

I know that these are meant to be used with the RCE yellow springs as an upgrade over the OEM shocks. However, my question is, the RCE yellow springs were designed to work with stock shocks/struts, so with the exception of a better damping curve, do these have a lot of head room to work with stiffer springs?

I guess my first question also leads to a second question, which is, will you guys be offering a spring that's even stiffer than the yellow springs to go with these GTWORX Bilsteins if they do indeed have a lot of headroom for stiffer springs than the yellow springs?

Keep up the good work guys!

It seems like the main reasons for going with this is:
- to use a much stiffer than stock spring (like RCE yellows)
- inverted front strut
- replacement of worn out stock bits

Anything else?

With the better damping profile of the stock dampers in the 2015+ WRX and STI, it seems the advantage of the GTWORX Bilstein is diminished a bit.

It seems like the GTWORX have been the ONLY higher end strut option available ever since the 08+. I hope you do provide this. Emphasis on compression damping (lower damping on rebound).

When the time comes, we will post the differences between the stock curve and our curve. I can assure you will definitely see and feel the differences with an definite attention to low speed compression and the transition to high speed compression.

Basically for me, please build us a D Street Autocross strut.

Would they be rebuildable? Sorry, I'm a Bilstein noob.

If you were to only buy the Bilsteins and use them with the factory springs, I'm quite sure you would still get a bit more dampening as they are being built for the yellow springs which are a little tighter sprung than OEM.

I don't see how this would be a negative performance wise.

And, in the last 25 years, I can't tell you how many people I have come across (internet and face-to-face and myself) who are willing to just drop in a set of springs without proper dampening. You live and you learn.

The WRX OE ride is a bit soft. It is very good. Don't get me wrong. It provides decent handling and absorbs bumps and potholes with no issue. However, it does not provide a sporty ride.

Short Answer: Yes i would buy them.

The WRX is my daily and will be over 50,000 km by spring 2016. This is a perfect bump in improvement while having the reliability and drivability required as a daily.

Please PM when release comes as i'm not often on forums, thanks!

We haven't finalized the valving yet...but...with some hard work we can improve both ride and handling for those on RCE Yellows OR stock springs. Initial testing of a first round prototype bears this out.

The standard shocks aren't bad, but there is plenty of room for improvements. When we get closer to that time we will share dyno plots and the thinking behind the damping profile we designed. I will get real nerdy in here, don't worry.

Hmm, how would these compare on the track against the Tarmac 2? I was looking at those coilovers, but I've heard great things about these dampers from previous models. So, Tarmac 2 vs GTWORX Dampers w/RCE yellows. Which is more suited all around for the track?

Well try to keep in mind that, that comparison is VERY lop sided. The T2's are VERY much intended for track and capable of being street driven.

The GTWORX/BILSTEIN set up is for sporty street and capable of doing track days.

2 opposite focuses. T2's rates are much higher and adjustable. GTWORX is set it and forget it.

With that said a GOOD driver on GTWORX/BILSTEINS will leave a intermediate driver on T2's seriously butt hurt and scratching his head after a track session.

as always, driver is key.

But I think you get my point right?

Sigh, here we go again. Products that are carefully researched and designed for our cars with attention to detail and the ability to use them in a DD.

First the RCE yellows, then the sways, now this Is there a frequent buyer program?

If there is anyone who is local to RCE ( Maryland ) or PA or VA, who is interested in a SOFT option I might have something for you. To be clear anyone who wants something SUPER soft in comparison to the stock STI or WRX shocks.

I have something from the "super soft" phase of development that you might like.

Call me.
