RX7 Brake Upgrade and Short Stroke Conversion Goodies!

Exchanged a huge chunk of last month's salary with these goodies last weekend.
Let's see what we have here..

First, i got the 80 series Land Cruise Brake Master Cylinder i need for my RX7 brake upgrade. I got the Aisin one, not the expensive Toyota OEM. I paid half of the Toyota OEM part and, as far as i know, Aisin makes them for Toyota. So, same stuff for half the price.
In case you're wondering, part number for the Master Cylinder is 47201-60530. Make sure to match the brake booster bolt hole numbers to your vehicle. There are two types: four bolts or two bolts. Mine is two bolts. This stuff is major upgrade for AE86s or Charmants, having one inch (25.4mm) cylinder diameter compared to the puny 13/16 inch (20.64mm) of AE86's.

Having no brake pads on my Ebay RX7 brake calipers, i also bought the pads coming from also 80 series LC. I learned that these pads should fit my RX7 calipers easily. I sure hope i am right..
With the caliper positioned as pictured, the brake pads measured 119 x 51mm. I got the Bendix General CT type which is suitable for general purpose driving. 80 series LC here have VX Turbo decal on the body, hence they're commonly referred to as Turbo LC as marked on the Bendix pack. *** update March 2nd 2011, see below ***

Next comes the u-joints for the propeller shaft..

Then the front steering links, explained previously.
and finally, the most important stuff, the front and rear dampers for my short stroke conversion. I'll discuss in detail for these stuff. Here's the front strut inserts: Kayaba Excel-G part number 365068 originally for Toyota Corona T170 series.
Shown above is the Excel-G compared to the original strut insert. You can see how much difference in length between the two.

Below is for the rear ones.
Unlike the fronts, these are cheaper Kayaba Gas-A-Just part number 553041, i believe they're originally for A60 Celicas. You can also see the length comparison to the stock orange dampers. These Gas-A-Just shocks are very stiff. I had very difficult time compressing to the minimum length when i measure it.

These are the measurements i managed to get for these dampers. I hope this is useful for owners of Charmants, AE86s or any other similar vehicles.
Front stock strut inserts (Part # found on the strut body is 48511-22190):
- Extended Length (E.L) = 645mm
- Fully Compressed Length (F.C.L) = 450mm
- Body Length (B.L) = 400mm
- Total Travel = E.L - F.C.L = 195mm

Front short stroke Kayaba Excel-G Part #365068 strut inserts:
- E.L = 540mm
- F.C.L = 390mm
- B.L = 340mm
- Total Travel = 150mm

Stock rear dampers. Found these markings: Kayaba Super-1000 SN8212 DL13
- Extended Length = 605mm
- Fully Compressed Length = 390mm
- Total Travel = 215mm

Short stroke dampers. Kayaba Gas-A-Just Part # 553041.
- E.L = 530mm
- F.C.L = 367mm (approximately, difficult to keep it compressed and measure)
- Total Travel = 163mm

Lesser important stuff obtained last weekend are these..
Front strut bar were borrowed from my brother, Erick. It was for Lancer EVO4 originally and as you can see, a bit too long for my Charmant. Well, another customizing job to put on the list i guess.

*** update March 2nd 2011 ***
The pads turned out didn't fit. There are two versions of these pads. The turbo and non-turbo pads. For RX7 calipers, you need to get the non-turbo pads which are smaller. You have been warned.

  2. I am building an AE86, have the RX-7 calipers and need master cylinder. What year land cruiser did you use? My project is turbo charged 4AGZE, supra 5 speed transmission with adapted bellhousing to fit 4AGZE, Celica LSD rear end. Engine was bored with forged pistons and rods, cranked turned.
