Sweet. I'm lowered 1" with my setup. Yea i do a lot of backroad cruising and those roads suck.

I went with 1-1/2" in the front, 1-7/8" in the rear. We decided to not use camber bolts in the front because we could rotate the strut spacer to get 3 levels of camber. The multi link spacers were very important in the back to correct for camber in the rear. During the install we found the spacers had pushed the rear subframe too close to the exhaust. The shop tweaked the fitment and was able to get a 1/4 inch gap between the two. The exhaust is the Invidia Q300 with 2.5 inch tubing. And now the pics:

Are these 16x7+35 Sparco Terra?

I can't speak for Turdinator's setup as he has an additional 1 inch lift, which will change body roll dynamics a bit. However, the 10mm lift that these setup gives isn't enough to drastically alter the standard driving characteristics of the car. The spring rates are actually higher than some lowering springs, but that is offset by the added ride height. Which means you wont be hitting your bump stops as often.. Overall the performance is better than stock, Swift lowering springs, and the performance package. The ride quality is better as well, and in my opinion a vast improvement over any lowering springs, standard package, and a slight improvement over the performance package.

The first comment I get from most people who rides in my car is that my BRZ rides way better than the last brz/frs/86 they had been in.

Seeing how I have used both the TRD Rally Spring & Strut combo as well as the TRD Rally Spring with SACHS performance package struts. I can say both are great for daily driving on public roads. Over all ride quality and performance feels better than both standard and performance package suspension.

The TRD rally struts are a better package than stock for all applications. The only characteristic that I felt I wanted to improve was that it didn't instantly settle after a big bump. It road over small stuff like nothing, but a bigger bump that would cause a chassis bounce would result in a small rebound before settling. I suspect this is the tradeoff when you have a strut designed for both tarmac and gravel.

Shortly after getting my BRZ I realized how good the SACHS actually were on the performance package. The car felt so much better than it had ever felt with the standard suspension. I opted to install just the TRD springs on a set of SACHS struts instead of the TRD Rally ones.

I am happy with the results. Overall I think the SACHS are a better match for daily, backroads, autocross, and track. I don't expect them to be as good offroad, but I don't think they would be that bad either.

If you are in an area with a good mix of dirt and tarmac then get the TRD Struts. If you drive mostly tarmac then the SACHS or possibly the Bilstein B6's are the way to go.

Sorry I missed this! I agree with abec's description in general. I haven't driven a twin with stock suspension for some time so I can't accurately compare I'm sorry. With my particular setup it is quite comfortable most of the time. That in part will be due to the baloon like tyres I have. From a comfort point of view I think the rear spring rate is a bit high and would be better being the same as the front. If the rear spring for the RCE set ends up being around 4.5kg/mm I may get them just for that.

From a handling point of view I am pleasantly surprised. It does lean a bit more and its not as sharp during transitions but the grip is there. With better wheels, tyres and some more rear camber I could imagine enjoying it on a canyon style run even. For reference beyond the TRD springs and shocks I have Pedders offset strut tops, whiteline camber bolts, Racerx adjustable rear upper control arms and the MCA traction brackets. I also swapped out the whiteline rear sway bar bushings for the stock units.

My alignment is about 1.5deg camber in the front and 1deg in the rear with 0 toe all around. I think with any toe in at the rear it would feel a bit too understeery.

I hope my waffling on gives you some idea

This is not great, right? It would be expected that a rally suspension has more travel. Buut, this could also mean that trd rally springs could fit on Sachs without giving unequal riide height change front to rear. Am I right?

Also: For those saying that this cannot be a good suspension for hybrid rallying because of the price: maybe this isn't very expensive, but it doesn't have any adjustments. So I am pretty sure the damping tune is spot on for the springs.

More total travel would be nice for sure, but hard to make a big change there without spending a lot of money. The thing about the stock suspension is that it's plenty of droop (extension) travel and not enough bump travel. Raising the car with springs like this doesn't add to the total travel, but you trade droop travel for bump travel which is definitely a worthwhile trade to make.

(if you raise the car too much with springs and don't have enough droop travel, that is bad too. that's why we're sticking with 15mm lift for our own RCE Rally springs).

Perfect, I understand the logic now. Thank you 😁

If you're interested in a proper rally setup have a look at the below link. This bloke has turned his 86 into quite the rallycross car with a lot of DIY work. Including long travel suspension.
