I haven't driven it much with the SSM axle back, hard to say if there was a noticeable increase. Yes, I had it on quickjacks and it was really easy to to do the job. Having it on jack stands, as long as it's high enough, shouldn't be too hard, I imagine. Hardest part really is getting the new mufflers onto the rearmost rubber hangers, had to pull them closer together. HTH!

Thanks! These particular ones are from DressUpBolts. My other sources are Racetech Titanium, MetteC, and Probolts USA.

Wow, talking about going beyond an extra mile. Off the charts, I am enjoying your work.

RCF calipers. No spacers on this version. I don’t like how that method pushes the calipers out by almost a half inch, designed to work with the RCF rotors. I will be using ISF 380mm rotors with this and will only require a thin hub shim to center it in the caliper. Painted the hub/bearing assemblies with some POR15 while they’re out.

Have you driven the car since you installed the under chassis brace? I had one installed and the stock cats would make contact and bang around so I took it off. Curious if you had any similar issues and if there are any solutions.

I have not. I'm still waiting for my headers and midpipe.

Awesome.. Any more spec details ??

I thought a bracket was required to bolt them up... How can the RC F calipers still work on the IS F rotors ??

RC F front rotors = 14.96 / 380 mm

IS F front rotors = 14.2 / 360 mm

Oh I will be using the 380mm IS-F specific rotors from FIGS/RB. The caliper spacers/brackets are needed if you are using the RCF 380mm rotors (factory or aftermarket) because of the disc offset. Otherwise, calipers themselves bolt on to the hub carrier without adapters.

What heat shield material is in upper photo?
The tape in lower photograph looks like Design Engineering 010416 or similar?
Curious. Thanks.

Hi. The tape is from ThermoTec and the starter heat shield is from Heatshield Products.

I was considering all of the same bracing. I bought the Fsport brace, and was looking at the rear and tunnel braces from Figs. Seem like areas that would all add plenty of rigidity without picking up a bunch of weight. What do you think about a front subframe brace? I don’t see them discussed or used much on here.
