Triumph Sports Cars

Well, the time has come to replace the front suspesion. As part of this process, I am looking online for bushing kits and front springs for the TR6. I am also looking for front disc brakes and calipers. Can anyone offer advice on springs? I plan to use a small block chevy, so to that end, should I use heavy duty springs or just go with the standard springs? Should I use lower springs or keep the same height?

As for disc brakes, where are you all buying these? The Roaster Factory, Moss, Richard Good...etc?

The question goes for the rack and pinion system... can anyone offer recommendations


Thanks

Toyota Cressida rotors and Toyota 4X4 pickup calipers.

Hello Art I have built dozens of TR sixes I would not use anything but Richard goods front bushings I run his lowering springs in the front of my car when I converted it to 347 the car sat higher than it did with the six-cylinder I had to remove one of the rubber bushings under the spring to get back down those parts you are looking for I would not go anywhere except Richard good I've tried at least four other sources all that stuff was junk compared to Richard's. As far as brake calipers go I run 1980 Toyota four-wheel drive pickup calipers 4 piston and they run on the stock TR six rotors you will have to make two changes for the Toyota camper you will need late-model TR six bolts they had a bigger shoulder on them I believe it's 74 and up you can use the ones that you have you just have to put a small sleeve around them and you have to make a new break line it will have your stock fitting on one end and metric on the other takes about 10 minutes

Or use Cressida rotors if you want them vented.

So what master do you run with the Toyota setup?
And what effect does it have on front/rear balance?

Another question would be whether one can still find these Toyota parts now, given that 1980 is quite a long time ago.

Hello ivor I run a Dodge Omni master cylinder that a straight 7/8 bore around here there in stock at any parts store they are all the same they fit other cars to you can get them on eBay for about $22 I will attach photos and you can see I run it differently I will not use power breaks power breaks are for cars over 3000 pounds for little old ladies driving them I do not know any racers that would run power breaks you have no feel in the paddle with power breaks these little cars just don't need them I did makes changes to the way the cylinder mounts see photo I moved the push bar up the brake pedal to get it more leverage that also makes the cylinder lay more level. The Toyota CalPERS if you run the 2 Wheel Dr. 1980 truck they are two piston almost identical to triumph the four-wheel-drive is for piston it will give you a longer pedal throw and move about 5% of the breaking to the rear everybody spends big money on fancy breaks and runs a power booster what a waste of money my brakes are so fast and crisp and clean and responsive and you can feel every stone in the road through the brake petal. I have nissan two piston disc on the back and they balance perfectly just got lucky even a blind dog finds a fire hydrant every now and then. As for the Toyota 4 piston calipers I paid $85 for the last pair I bought and that was with pads those calipers also fit a lot of years I always say 1980 because I can remember that I'm getting old I think they use them for another 10 years very common parts if they were aluminum like my reers they would be perfect. For a plunger on the master cylinder round off the Tip of 1/4 inch Allen had bolt and it fits perfectly in back of the master cylinder you double not where it screws into the plunger and you have paddle height adjuster. Signed who needs breaks anyway

Ivor, You would need the 86-88 Toyota 4X4 pickup 4 piston caliper(S12+8) for the 86-88 Toyota Cressida Sedan 10.7 vented rotor.

Hey Jim the older Toyota pickup didn't have ventilated rotors the 1980 Toyota had solid rotors just like a TR six I personally have never found a need for ventilated rotors the car is only 2100 pounds I do not know what year the Toyota truck changed.

Signed if it's just bolted on you probably don't need it

I think they switched around 85. Your stock TR6 rotor with earlier caliper works fine. The vented rotor is an upgrade. You can even use the finned larger V6 FourRunner calipers too if you go up to a 15/16"master cylinder. You can also use RX7 calipers with a simple bracket. This thread is for converting a MGB but has lots of info and pictures. [forum.britishv8.org]
