I remember reading on special stage or dirally that Maintenance/overhaul can get spendy as well.

I would be interested in a set of slightly taller springs, provided the spring rates are acceptable.

TRD makes a set of 10mm taller springs, but they too stiff (4.55k front, 5.15k rear) for me.

I am looking for somethings taller (+10mm to 15mm), with spring rates of about 2.5k front and 3.8k rear.

By the way, after installing taller springs, how should be adjust wheel alignment to compensate?

My wild guess that due firmer springs in rear one won't need more camber in front to get more oversteer, so no more usual "by 0.5deg camber more in front".
As for 10mm higher TRD spring .. imho it should be used only together with TRD rally damper, which completes the set. I don't think those springs were made to be used with stock shocks.

That's pretty awesome.

Those TRD rates are quite stiff. We definitely wouldn't be that high.

We weren't planning on going softer than stock. We'll see though.

For alignment you don't need nearly as much negative camber on a loose surface with less grip. You do still need some, and it depends on exactly what type of driving your doing and what your tire choice.

In general, real stage rally dampers don't use a lot of rebound damping. You can see in the Kubica test the tires mostly stay on the road over some serious bumps even while turning and cutting through corners. They extend back down to the surface easily instead of being held up as they would be with lots of rebound.

On the other hand, compression damping can be quite firm. The really good stuff is digressive while adding an extra end of a stroke adjustment, and/or with the right shock piston the very high speed compression damping is tunable independently (I'm not talking about conventional high speed compression damping). The idea being that lots of low speed and digressive blow off like a track coilover is good for control and for soaking up bumps, but you do want extra high speed compression to prevent bottoming and especially if you're taking your WRC car off sweet jumps.

All that is to say that don't expect a WRC level performance from your OEM shocks, but you can still have a really fun time. I would expect Bilstein B6 to do even better.

I'm down. Will the b6's handle the 15mm hight increase without any custom work?

Yes for sure.

- Andrew

From what I am reading, Bilstien makes rally inserts for the HD shocks. This could be an option for those that need something a little more than rally cross but don't need full stage rally setup.So b6 and spring deal if this happens?

Racecomp Engineering: btw, what do you think of designing some simple as possible engine protection plate, that has ski like front side, that would go over lower part of front bumper, and would be simple to mount/unmount (for example some hook like attachment below/rear, single thumbscrew front, to quickly mount it before "starting to have fun" and mount/unmount without having to lift car, when one drives back home on normal roads. It should also simplify going above snow piles, while stock bumper bulldozer shape would tend to dig in). I'm not thinking of some real strong aluminium plate or even CF protection of car & engine with multiple strong attachment points to frame that can held against really heavy hits, as it won't be for real rally/rallycross, just so, slight protection when sliding off track. Otherwise ending with nose in deep snow pile may mean relatively expensive damage to bumper & maybe rad/conditioner heat exchanger (hopefully for non pre-MY2014 car when it was for use with very expensive 1234yf gas), even if speeds were low and "normal cars" would have slide above with near to no damage at all.

Yes.

This would be great, but is outside our area of expertise. There are a couple US shops that do things like this for Impreza but I don't if any have BRZ parts.

There has to be more than a handful of people

I would love a set of these to beef up my winter setup for the snow here in North Dakota. Still waiting for my yellows to come in and I'm sure I'll love tho too lol

Very interested if the spring rates are on the lower end, or progressive with softer initial displacement.

100 Acre woods rally is going on today, good day to keep the discussion alive.
