Default Re: WARNING: RE RSM's and Koni 1159S not compatible!

White-hot, I've decided to go with the koni externally adj rear's, koni fronts, and H&R OE sport springs. I hate that the 1159S's won't work with the RE RSM's, I had JUST picked those RSM's out, then remembered something about you having problems with them. However, looking at the TCKline version of this setup, it looks like they do not come with a dust cover, hence can come with TCKline's version of the RSM similar to Roque's. So many choices. FYI, I've found the 1159's for ~180ea, so I have to call tomorrow to see if they are in stock. So using the 1159's, I'm about $180 under the cost of the TCKline kit.

Question, with the TCKline shock being a longer shock (at higher cost) than the 1159s, think the additional oil volume would help under extreme's? (I'm looking for a reason to justify the extra $180 if i can't find the 1159s's in stock )

Here's the TCKline kit w/o dust cover and w/their 'upside down' RSM.

Here's the TCKline kit w/o dust cover and w/their 'upside down' RSM.

The TCK rear shocks do come with a bumpstop and a cover. They work just fine with the RE RSM since the cover is a good bit smaller and therefore does not interfere with the mounts as do the 1159S's. That kit is more expensive due to the TCK markup more than anything. You could likely come out better money wise sourcing the items elsewhere, but it is convenient getting everything in one place.

The TCK shocks are longer, the same length as the OE shocks, but this will have no effect on performance at extremes. The only difference is that the 1159S's don't droop as far and will top out quicker over uneven terrain, something I found out quickly and commented on in the review. The performance is controlled by valving inside the shock more so than by the quantity of fluid. In fact, the TCK 1200S shocks are gas shocks, unlike the 1159S’s which are hydraulic. If the prices were the same I would prefer the OE length shock just to avoid the top-out issue, but as it stands I have learned to avoid the problem.

I can only say that I love the setup I have now and whole-heartedly recommend it to you. If you can save some money in the process, go for it. The RE RSM’s are nice, but are not the only nice ones out there. If you choose to go with the 1159S’s then buy a top-mount RSM of good quality that can handle the 12mm shafts and call it a day. The JT Design ones I got from Turner work just as well for the same money, though you will have to find the washers with the 12mm holes to make them work.

Good luck!

Thanks white-hot!

Hoping to get one more question in before the server goes down .

It looks as if there are 3 thicknesses for top spring pad for the rear shock; 5, 7.5, and 10mm thickness. Anyone have a recommended thickness when used with the HR OE springs? I'm tempted to go with 5.

Go with what you have. You do not need to change it unless it is badly damaged. They are very tough pads so I doubt you will need to. I do not remember what the stock thickness is but IIRC it is the 5mm.

Well crap, I ordered these RSM's from Turner Motor Sports:

http://www.turnermotorsport.com/p-15...3-z4-pair.aspx


And they send me these:

http://www.tcklineracing.com/webdocs...Details390.cfm


Going from the picture of the TMS RMS, I was confident they would work with the 1159S rear shocks. But. Oh well. I guess I'll return to TMS and go with something else. Or I could just get a set of bolts to bolt up through the bottom and use normal reinforcment plates.

Aside from the anodizing, is there a difference?

Yes, the Turner's as pictured above are 'bolt pointing up'. The TCKline's as pictured above, are 'bolts pointing down' (and captive in the reinforcement ring, which is a quite nice design IMO). But, with the Koni 1159S's, you can't use the 'bolt pointing down' RSM's due to the large metal dust cover (as discovered by white-hot).

Thanks. I didn't catch that. If the bolts weren't captive, I guess that wouldn't be a problem.
