Parts Shop Max subframe and differential risers
I know these have been out for a little bit now, anyone get these yet?
"MAX SDR and SFR's for FRS/BRZ are not violent, nothing like solid engine mounts which would shake the whole car. The feel of the car's suspension over rough roads is unchanged, its largest change to the driver is the application of the clutch is no longer soaked up in those bushings its applied more directly to the wheels. So when you do a clutch kick instead of doing nothing, you can actually initiate a drift using the stock motor. It makes a handling improvement on lowered cars through roll center correction by returning the arm angle towards their original position and it makes the axles last longer since the CV joint angle is made less severe. The diff is a lexus unit with oil filled bushings which pretty much eliminate all noise, so when you install all the bushings its much louder. It could be hard to carry out a bluetooth conversation while going 90 mph (you probably should not be doing that anyhow), but its actually a cool sound comparable to a supercharger since its an RPM/speed dependent sound. Like a muffler it lets you hear your car where you can shift without looking at the tach. The sound is inside the car because its transmitted through the unibody, nothing on the outside of the car because theres ambient noise & the air is not a very good conduit for sound versus the solid stricture." Differential Risers "The axle angle is so bad when this car is lowered that it puts a lot of strain on the axle joints. This bushing set eases the angle of the axles on lowered cars by raising the diff 20mm. Bolt on CNC aluminum gold anodized front bushings and Weld on laser cut steel subframe/rear diff mounts with new hardware. The FRS and BRZ use a lexus diff and also the luxury oil filled rubber mounts that are great for canceling a lot of noise, vibration, and harshness from the luxury car but they are doing you a disservice getting the power to the ground in your sports car." Subframe risers "Get rid of the OEM Rubber bushings that prevent you from getting all of your power to the ground! Help your axle angle and roll center on your lowered car with these CNC bushing replacements. See the forum for install example. ~ The silver M14 washers are used under the OEM bolt head, 2 in the rear one in the front, when you dont use the gold 5mm topside spacer. ~ Dont use the topside spacer for maximum roll center correction. In this case you need to grind excess metal as seen on page one of this thread. ~ If you cant grind your SF and just want solid bushings not Roll Center correction, or your race rules forbid modding the SF, use the topside spacer, and just use one m14 washer under the head of each OEM bolt. ~ Pair these with the diff risers to make your axle joints very happy on your lowered car."

Is it just me or do these risers just look like solid subframe and differential bushings?

The difference is they are shorter and therefore mounted higher up.
Risers. |

i assume that unlike the whiteline stuff, these need to be pressed in, which means complete disassembly?
having said that, i think this is a must for anyone who is lowered... it solves a lot of the geometry and axle problems no doubt... cheaper than making a custom crossmember (900-1000 bucks) which is what most other cars would have to do.

Did you notice a sound who come from the rear when you take back the gas after an up or down shifting?

I know I have the Whiteline insert and I noticed a sound only after tap the gaz pedal after the engine compress... then I wanted to be sure it's normal.
Are you able to provide pictures of your set? Am curious to see what they look... Maybe mounted on the car too.

Last pic, you can see how close the DS is to the top of the tunnel. This is as high as it can all go, without cutting the tunnel up etc. |

Very Nice job, hopefully you have more NVH cause of the diff insert , it's my next step.
Then the DF moved a little bit to the top with your diff inserts?

Oooo I have seen now, the subframe is directly on the body... Then everything have moved to the top.
Also, Nice sway I have the same setup...

I don't think my NVH will be more or less because of the diff insert. The inserts are bloody tight, needed to be pressed in.
