Thanks Pete, I couldn't get through yesterday but ISAIAS hit us pretty hard here and most everyone is out of power.

You can see my thread on rennlist (search my user name there and look for 964 thread) with lots of details.

But, to keep it simple i would use the ERP monoball inner and ERP bump steer outer with the bump correction. Order the spec for the setup you have. Ira at tarret sells and will make sure you get the right parts.

The main issue is the stock rods are too long due to the steering linkage placement

So I was looking at your 964 build thread on Rennlist, and I wanted to know if looking back you wish that you had gotten different parts for your suspension or done anything different? I am getting ready to order parts and wanted to learn from your mistakes if any before I pull the trigger. Thanks!

I've been thinking about this and offsets etc. using the 993rs carriers must narrow the track width. That is the only way to explain the inability to get -3* camber when it is totally possible on the stock uprights and stock top mounts. Then the 993 longs give it back- but no one has determined how much the uprights actually narrow the track. It may be almost a +- 0 with the combo of the 2.

That said I'm on the fence- grind or 993 longs. On reason is that I want to go with rennline sealed bearing camber plates that also have a shield the keeps water etc from coming though the adjustment slots. Those probably won't give any more camber even if you grind the sheet metal.

If you cont need 3* then its a no brainer.

Pete

I recently swapped out my uprights to the RS on my track car and there appears to be no difference in track width.

Then how do we explain many not being able to get enough camber with them on NB cars?

Camber shouldn't be impacted by which settings are used. I have no issue achieving the camber I want with them. The hats on the other hand require some modification of the top mount if you are using the ERP/Tarett or whoever makes it design. I am assuming this must be what you are having issues with.

So is one specific camber plate better than the others when you are putting RS uprights on a NB 964?

Elephant Racing, ERP/Tarrett, Rennline, etc.

There are many accounts of only being able to get 1.5* after installation of the 993rs units. The top camber plates Spyerx used (that he linked above ) will give enough adjustment if you grind the body a bit to get the full range if adjustment. It seems that it comes down to either a bit of grinding or 993 longs.

Pete good point. I didn't take into consideration I am using 993 longs on my wide body 964 so this accounts for it being a non issue for me. Sometimes I have to go back and re read a thread I think I am suffering from onset Alzheimer's or just old age.

bighead. The Tarrett units are basically a copy of the factory 993rs units https://msroadrace.com/Porsche-993-Front-Camber-Plates-99334301780-99334301880-99334308180-99334308280 help a little with caster as well as camber. They rotate around a single point with 2 adjustment screws vs sliding in and out on 4 bolts as the other designs do. The downside as noted is if you want a lot of camber you will need to grind the towers or go with the 993 longs as Pete said.

Just want to point out- and I'm not sure why but Spyerx's ERP plates have a TON more adjustment than the ones that cobalt linked


stolen from Spyerx's thread (hope that's ok...):



vs Cobalts linked:



and just for contrast a more standard camber plate from rennline(what I'm leaning toward):

The ones I linked to are the factory 993 plates. The Tarrett plates offer more adjustment. I was just using those as a comparison to the design which was originally done by Porsche and copied. Although tarrett doesn't make these there is a company overseas that makes these and distributes to multiple suppliers as are many of these products.
