GTR Coilover sleeves

This is another post from COBB Tuning.  However, unlike the other 2 blog posts, I did not make this one.  COBB Tuning GTR Coilover sleeves But it was a product I designed and tested.  There is a couple reasons we went with sleeves instead of full coilovers.  First, we knew we were going to eventually make coilovers, but we also know those are not something you can throw together in a month and get right.  And we needed something to race on, and we needed them fast.  Second, the stock shocks are a pretty advanced system that is cockpit adjustable and we knew people that owned GTR’s would like to have that user-friendliness and softer ride than what aftermarket dampers provide. Third, and least important for GTR owners, was they are much cheaper than a full coilover and damper set.

Here is a couple shots of the original version.  I made quite a few changes after this version to make them easier to install and work a little better.  But I don’t have a good picture of the final version, so this is what you get:

I made the kit have spherical bearing top mounts that use a nice FK bearing that is fully captured with stainless steel bearing spacers.  The way I made them allows the springs to move independently of the top mount unlike some others.  Also, it has helper springs with some nice trick spacers.  And another thing I hate that some people do is lock the spring perch in with a setscrew or another perch.  So I made them lock in place with a slot that pinches closed with the use of a stainless bolt.  I also decided to use Hypercoil springs because they make great springs.  And they have the best guarantee in the business as far as springs matching the rates you specify.

Not sure what else can be said about these.  They work great.  They are what we race on.  And we have had 0 troubles with them since we started.  So if you have a GTR and want to keep a nice ride and your trick stock shocks, have we got a coilover sleeve for you 🙂

Looks like they haven’t been added to the site yet.  But keep an eye here: COBB Tuning


MazdaSpeed3 3-way suspension testing

So here’s another “I posted on that other blog” post.  This one is about suspension.  Which I personally think is a lot more fun to design and work on than upgraded GTR turbos.  Not that those aren’t cool.  It’s a GTR, working on anything for it is cool.  But this suspension is just awesome.  It’s 3-way adjustable.  So in addition to adjustable ride height, you get low speed compression and high speed compression and rebound adjustments.  All with external reservoirs.  Now to go into the nitty-gritty of why these are so cool, I would have to divulge some proprietary info that I am not willing to do.  Here is what they look like:

This set is for the MazdaSpeed3.  I love those cars and we have been racing on springs and sway bars I did for it for quite some time.  And while we do amazingly well with what we have so far, I think these will help us a bunch.  I don’t know if there is enough of a high-end market to justify selling these in a 3-way to the Mazda guys.  But we will have 1-ways that are just as sexy.

Other applications I am working on are: GTR, EVO X, STi (both old and new), and hopefully the Z someday since I would love to put a set of these on my car.

These things are bullet-proof  So beefy and strong.  I can’t wait to release them.  Stay tuned to COBB Tuning’s blog and website to fine out when they are available.

And here is the main blog post at COBB’s blog: SEXY ASS COILOVERS

My first post on that “other” blog

So as of today I am going to start being a regular contributor on the COBB Tuning blog.  And if I knew what the hell I was doing, I could make that post show up here.  Until I figure out what I am doing with blogs, you will have to deal with a link: COBB Tuning upgraded R35 GTR Turbos

Here are some teaser pics:

Here is a run-down of what it covers.  The stock Nissan R35 GTR turbos are good for about 520ish HP at the wheels.  Well, we took those and stuck a compressor wheel in it that is theoretically good for maybe 180-200 HP more.  Now due to other limitations in the engine, we don’t expect to make that much more.  But it’s good to know those turbos should be able to deliver a lot of power at some point.  This was much more complicated than just machining the housings out for bigger wheels.  I can’t really go into all it involved as that is all top secret.  But trust me, these should be cool.  We will be testing them very soon.
