Has anyone corner balanced S2 sport?
 

Can you share your corner weights. I transplanted S1 corner balanced suspension on my stock S2 (sport trim)

just want to see how much different is the weight distribution between S1 vs S2

below is what the original owner had done with corner balance on his S1

If I understood you correctly, it seems like maybe you don’t understand the basics.

If the suspension was swapped onto your car then you have to go have it corner balanced. There’s not going to be any way of knowing what the result is otherwise because that process is unique for every car/driver combination. No two cars are dimensionally exact, exact weight distribution, driver physical weight & position differences, plus depending on how the suspension bushings are loaded on your installation compared to the other car, and so on. Lots of variables. That’s what the corner balancing process accounts for.

which on a saddle fuel tank car it also depends on fuel capacity and volume in each saddle. The best balance will be with a full tank, but then you have the weight penalty. Generally speaking within the realm of those percentages, lightest weight always yields best potential performance.

.

obviously having it corner balanced again will yield the best results, however I would think there isn't that much difference in the weight distribution between S1 and S2. This is Matt's suspension and we installed it same way on my car like he did on his with same preloads.

I took car to Summit Point last weekend - Shenandoah track is know as miata track (very technical) and car drove very well - neutral and nicely balanced and this is without me aligning the car after the suspension swap (could not get it on the alignment rack at the local shop).

I am just curios to see what stock S2 corner weights are if anyone did corner balance

I also did measure the ride heights and they were as follows:

Front L R
13 1/8" 13 3/8"
Rear L R
13 3/8" 13 7/8"

so I will probably need to add a bit more camber to the right side, both front and rear. My driver side front is already set to max neg camber car can have.

Well, I tried ... :dunno:

S1s and S2s aren't the same. S1s are a bit lighter, so that's going to change, well, everything in a corner balance.

As per the other posts, it's going to be different, but I just happen to have what you asked for...

2010 s2 sport, with 17x9 enkei rpf1 with 255/40/17 Direzza Z2 tires and coilovers. I think it had a BHR midpipe as well, and 140lbs of driver (don't recall exactly if both of those were in at the time) ~13.3 inch ride height front and rear. Not actually corner balanced, just weighed after setting all corners to the same height and an alignment.

EDIT: This was actually for a completely stock s2 sport with 1/3 tank of gas and 140lbs driver. As it sat on the factory suspension and wheels. 49.7% corner weight from Mazda. Not too bad :-)

great, thanks.

I believe numbers from S1 are with driver (~180-90lb) in the car but without wheels - scales attach to the hub. I am guessing ~45-50lb for each wheel.

so taking wheel/tire(~50 lb) off your S2 weights gives this differential in corner weights of S2 vs S1:
806 vs 775 (+30lb) 759 vs 799 (-40lb)
695 vs 771 (-76lb) 665 vs 635 (+30lb)

interesting to see this much difference for pretty much same car, especially on the left rear.

Not really. Everybody is telling you that every one of our RX8s will be different based on the particulars of that car. That doesn’t even account for potentially faulty or mis-calibrated scales and a wide variety of other factors that can contribute error into the readings. Fantasy cornerweighing doesn’t work. Not to say you can’t make a lucky guess once in a while.

Add two turns on the left rear coilover of the s2 and the numbers might be a lot closer though.

Lol. Those aren’t his numbers. Those are from the prior car that the coilovers were on.
