Did a minor rear suspension upgrade on my Deuce.

pretty sure those are techo toy tuning

I had techno toy tuning make them for me. They should have them in stock now for the Rx2. I have been sending OEM parts to upgrade.

 

How much for the rear coil overs , and do they make them in different shock options ?

 

They cost me about $700 and change. I didn't ask about other brands.

 

Yes, we can provide the rear coilovers with the AGX shocks (adjustable) or the Bilstein dampers. The 4 links and Panhard are available on our site now as well. Much thanks to Reggie for helping us develop these parts.

 

Didn't know anyone made them, I had to make my own from scratch. For the rears I used megan racing struts and then lathed down Toyota top hats and redrilled bolt locations.

 

Guys I am just curious . How is the quality of the ride (for street use) in your RX2 with a coilover set-up. Most coilover setups tend to ride on the harsh side. Any feedback appreciated as I considering a suspension upgrade for my deuce

 

I don't think coilovers ride are harsh. Most of US like a firm ride. You can pick your spring rate and the dampening is adjustable.

 

What is a good spring rate for street use and what is a good dampening setting? I am in Maryland area. The major roads are decent. Secondary roads are average in terms of potholes etc. I know this is a personal preference but any feedback based on experiences will be helpful.

 

You cant just always change springs as suggested. The reason is that 95% of coilovers out there are for a harsh stiff performance ride. They do this by running extremely high pound per inch springs with a short length. I have several makes and models coilovers , cxracing, megan racing ect.... and all came with 450-550 lb per inch and all were between 6" and 8" spring length. With these systems the actual shocks are set up to have average 3" stroke. As you lower your spring rate you need to have more stroke on the shock. Street cars are usually set up around 40 to 50% of stroke at a level stance, so this means with some coilovers you will only have 1.5" of shock travel which is ok with a 500 lb spring, but when you start putting in lower rated springs you will run into damaging the shock.


another way to look at this is that 3" of travel with 500 lb springs gives you 1500 pounds to bottom out, with a normal street spring around 200, this gives you a total of 600 pounds. This is why lower rated springs need more stroke, 200lb springs should use a 8 inch stroke shock.
