I'm looking into stiffening up my rear suspension and I came across these and I was wondering if anyone had used the SR drag launch kit. From the description it seems like all it is is a couple of nice urethane diff mounts and a complete bushing kit for $455. Now that seems a bit steep especially when compared to a complete bushing kit from Mazdatrix which is $141.46 + 2 competition diff mounts(not urethane?) at $53.65 a piece. So, from mazdatrix the total would be $248.76 vs SR's $455. Anyone have any experience with the SR kit? Are urethane diff mounts worth that much more than mazdatrix's "hard rubber" diff mounts? Is there more in the kit that that or is their price just 2x as much for no reason?

Anybody?

 

I haven't seen the SR motorsports drag launch kit, BUT they are known for their high prices and shady advertising. If you search their name you will see them selling turbos as secret spec KKK turbos to the 3rd gen guys for exorbitant prices even though they are a garden variety lower price relative to KKK (Schwitzer was it?).

I have a clean brake-away of traction for street radials with poly suspension bushings and comp. diff, trans,motor mounts, engine torque brace and a JIC Magic Carbon rear strut tower brace.

I can't believe the difference the strut tower brace made in the rear! I added it las and it REALLY helped quell the wheel hop as well as helping the rear end rotate on throttle lift (hard to get FC to do). I was surprised.

I still need to add comp subframe bushings or get the slip on alum busing isolators that are popular in Japan (those slotted pieces you slip above and below bushing w/ subframe bolt loosened to eliminate the bushing movement.) That shoud totally eliminate the slight shuddering I have now.

I also need some trans torque brace (like 3rd gen power plant frame?) as the shifter still moves too much making shifting from 2nd to 3rd harder (once you pull it out of 2nd the trans moves from being unloaded and where 3rd was isn't anymore- damn.)

 

i heard the strut brace does help quite a bit....

 

Hmmm, I have a vert. I think I recal reading that they have something of a rear strut brace built in. I could be wrong though.
