All everyone needs is a little push.

How'd you cone up with these increases? I couldn't figure it out, but have always been curious.

Thanks,

Ohhh yea, deflection! I forgot about strengths of materials and statics.

I'm sorry to resurrect this thread. I will be almost a year into my CPO 2015 NX200T FWD and so far happy with this all around DD for me. One thing it does do is wallow in faster corners (like freeway exits). A number have done this upgrade - is the consensus that it's worth doing?

If you asked me back when I originally posted this thread, I would've easily told you that this rear sway bar was a great first mod. Since then, however, I have been able to do more suspension work on the NX.

Knowing what I know now, the best bang-for-buck handling and anti-roll mod is Timbren's off-road active bump stop/suspension enhancement system for Jeep Wranglers, part number JFC01 available , installed in place of the factory rear solid bump stops. It stays disconnected when you're driving straight, it gets in contact and almost doubles rear spring rates when the body rolls around corners. It's very durable, and about the only knock about its longevity you'll find online has to do with side shearing of solid axle suspensions, which doesn't really apply to our vehicles' rear suspension architecture. It's a lot easier to install than the rear sway bar, too. Please see the photo below for a comparison between the Timbren bump stop and the factory bump stop.



The only issue, if you'll consider it that, I encountered with this part installed and in combination with my other suspension bits is corner exit oversteer when pushed VERY hard. Seeing you mentioned that you have the FWD, I don't think this would be much of an issue.

Supporting parts and tools you'll need to get the job done:

14mm, thin-walled spark plug socket - the hole on the middle part of the rubber spring is too narrow for standard sockets
- the included metric bolts suited for the Jeep (strange that it's metric) has standard M10x1.5 pitch, while all Toyotas use fine M10x1.25 pitch
Blue thread lock
Plumber's wrench to remove factory bump stop

This shows up as a FRONT bump stop replacement. You're recommending it for a rear installation?

chezgk

They only listed it as a front replacement because of the included spacers, which incidentally is a perfect fit for the NX's rear. There's no front or back associated with the individual rubber springs themselves. They're universal, and Timbren has a catalog for just springs people refer to when fabricating their own kits. Hope this clears things up!

jsmith

Totally doing this. Ordered the Amazon item and took your advice and got Allen head bolts instead of the hex heads for ease of installation! Will update with results of this little project. Can't wait to take that little sweeper on the highway with this on!

chezgk

Keep the board posted! If you find it as effective as I did, then a new DIY thread might be a great idea, specially since this keeps the factory ride unlike aftermarket rear sway bars.

jsmith

The Timbren kit came in right away. When I went to look for the delivery status on the allen head bolts, turns out they are coming from the UK urrrgghhh. Can't find any local suppliers too!

chezgk

Must've shipped from Bolt Base UK. With the Timbrens in hand, now would be a great time to check if you ordered the correct length Allen head bolts. Keep us posted!

jsmith

I ordered 70mm like those bolts in the link you posted. I just measured the kit and it has 90mm bolts. I don't think it will be long enough as there's only about 30mm protruding past the spacers....

chezgk

Confirming that I used 70mm on mine. 10-15mm of engagement is enough, as the load exerted on the bump stops is just vertical. Anything beyond would just go through the threads and to the void above them. This will be apparent once you have all the parts laid out in front of you and commence work. Cheers

jsmith

Well, the 70mm are still winging their way over here. I got 90mm's from FMK, it might get here quicker ;-)
