    Re: 1990 Consulier GTP Targa

    I ordered new brakes today...brake lines, rotors, calipers, pads....all for a mini van.
    These stock ones are the regular Daytona style, not the Shelby ones.
    These are 10 inch, the Shelby Daytona ones are 11 inch. I ordered the mini van
    11 inch ones. Should be a nice upgrade.
    Here are a few photos....
    Front sway bar endlinks were toast.
    a shot of the suspension, minus brakes.

    I fit the 225-50-15 tire on my 8' revolution wheel. Will not work on the front. Too wide. Now I am headed off to the tire store to put the 205.50.15 on the 8" wheel to see how that works out. Post photos later.

    - - - Updated - - -

    Put the 205 on the 8" wheel and that will work. Will run 225's on the rear, 205 on the front.
    The teal wheels (6-1/2") with the 205's on them, the tires sit 1-1/4" inside the fender.
    The black wheels (8") with the 205's on them, the tires sit flush with the out side of the fender.

    you can't just bolt 11" minivan brakes on a 10" spindle. unless the spindle is a 91+ spindle.

    - - - Updated - - -

    What you can do is bolt the 10" minivan calipers and pads to the earlier 10" spindle using the correct adapter bracket and this is an upgrade because of a bigger piston and pad area. The later 11" brakes require a spindle change.

    Thought you just had to change the bracket. The 89 mini van has a 11" rotor etc.

    On 91+ spindles yes, you just change the bracket for 11's. On earlier spindles NO, you can't just change the bracket for 11's. Caravan brakes on early spindles are still 10" but you change the the bracket and caliper and pad for a bigger caliper and pad. Known as SLH1 using these parts 60mm / 40% conversion

    BUT this is geared toward L body cars. Doesnt that change things for a Daytona?

    Nope, because they used the same spindles. THey just wrote it for the Lbodies because they had the crappiest brakes stock. Doing part 1 and part 2 in that link just brings you up to Daytona levels of brake hardware.

    L-body's and Daytona's used different hub/spindles. You cant put a G body one on a L-body without much modification.

    Re: 1990 Consulier GTP Targa

    From what I can see, you have the pressed in bearing and the caliper carrier bolted to the front knuckle so that means 10" disk.
    So if you would like to go 11", you will need the front of a '89-90 Daytona Shelby or Lebaron GTC. Bearing would be bolted instead and the caliper will bolt directly on the knuckle (no carrier)
    '91 up can still be had in 11" but need the specific caliper, the carrier, and the knuckle.

    How about pictures of the back, Johnny?
    I really like the in depth of your pictures since I doubt that I will own one someday.

    That's the cantilever suspension?
    What brand are those coils and shocks?

    Re: 1990 Consulier GTP Targa

    So, I'm kinda confused, Johnny. Are you going with 11" brakes or 10.25" brakes?

    The way I understood things is that you can use 1st gen Caravan calipers, pads and rotors on 5x100 cars as long as they were 10.25". The difference being that the caliper has a larger piston, the pads are slightly thinner, but the rotor is thicker with more fins for better cooling.

    You can go a step beyond that to the 11" brakes, but that is either only from the '89/'90 performance cars, or the '91-up performance cars and vans with 15" wheels (you have to use car rotors and spindles due to bolt pattern differences). Both of these would require a swap of the entire upright. The '89/'90 ones are unique to those years of 11" brakes as the caliper adapter is cast into the part. The '91-up ones, you can use any car upright, you simply have to bolt on the correct caliper adapter bracket.

    Trying to go 11". I want over kill brakes for autocross and track days.

    The '89/'90 ones are unique to those years of 11" brakes as the caliper adapter is cast into the part.
    Okay I bought parts, I am starting to see if it all fits together. I bought 11" rotors (5x100) to go with the 89 2-pin Caravan calipers.
    (I bought 89 Shelby Daytona 11 inch rotors) I have some 2-pin knuckles from a car/van I parted out that I will switch to.
    I'll see if it all fits and will take photos.

    I will when I get to them.

    Re: 1990 Consulier GTP Targa

    Go with 91+ knuckles. This will improve handling even more over the improved suspension. Once you get the 91+ plus you cans buy everything for the swap. The bolt on brackets, calipers, and rotors are all still available. You can use any 91+ knuckle no matter what brakes they came with.

    Also there are more pads available especially the hawk pads.

    Any 91+ knuckle
    Calipers and brackets for a awd caravan(bigger pistons)
    Rotors for a spirit r/t
    Wheel bearings from any 91+ car.

    Re: 1990 Consulier GTP Targa

    Did the front brakes today. Worked out great. Used the knuckles I found in my storage.
    (I think they were from a G body)
    Had the used rotors turned. Here are some photos from the project. One photo shows the
    numbers and brand of front shock. One photo shows how much larger the surface area is
    on the upgrade brakes from the Caravan.
    That bolt is the pieces they used to go through the place where the axle normally would have gone.
    The hoses...the same as any k-car, Daytona, Shadow, Caravan... except had to take the bracket off.

    So you went to 15" van wheel brakes or 89/90 Shelby Daytona brakes. Looks good, Gonna do the back ones the same? Need to keep the brakes matched and more rear brake than a FWD car since the weight is in the back.

    Chrysler knuckle and rotor and brake line. But Fiero brakes? I am checking with a Fiero guy.....

    - - - Updated - - -

    Confirmed....these are 1988 Fiero rear brakes. A one year only item.

    I would NOT use the '91-up uprights (aka knuckles). The reason being is because this suspension was designed around the older style upright. Remember, this is NOT K-car suspension. While it's true that the '91+ stuff has a larger off the shelf selection, that doesn't mean there aren't options available. A lot of your racing pad suppliers will re-puck pads with whatever compound you specify.

    Johnny, that means that you can make the brakes absolutely WAY overpowered for this car very easily. They claimed it would pull down from 60 in about 100' already. I'm assuming this means with slicks and racing pads that are up to temp, however.

    - - - Updated - - -

    Johnny, take a look at the dimensions of the uprights where the tie rod attaches. It might just be the picture, but it looks different. If it is, that could cause bump steer or Ackerman issues.

    It looks like he used '89 11" brakes to me (bolt in wheel bearing, integrated caliper)...

    Assuming that the original is a "normal" 88/89 kcar knuckle then the geometry should not be negatively affected.....

    Plus the only difference between the geometry of the 91+ knuckles is that they push the ball joint downward (a good thing) so I don't see an issue with the geometry. I would prefer the 91+ knuckles because you can easily change between 3 different brake biases.

    • 10" with 54mm calipers (normal kcar)
    • 10" with 60mm calipers (van with 10" brakes)
    • 11" with 60mm calipers (car with big brakes)



    All by changing just the caliper bracket and caliper and the rotor without changing the spindle or doing an alignment
    Note: It might then also be desirable to change the master cylinder to correct brake pedal travel.
