    How To: Cheddasauto Front Top Hat Installation Guide

    The purpose of this write up is a guide on how to install the CheddasAuto Top hats. Ive done my suspension couple of times but this was a first for me and for many members. The reason why top hats work is to extend the suspension travel with out bottoming out the shock. works good on lowered cars. I went when a Koni yellow shock from the 1988-1991 Honda Civic. For coil overís I went with Ground Control because they make a kit that fits the koni Yellows. For the front springs I got a 7inch spring with a 440 LB spring rate. I also picked up Prothane urethane bushings for the top hats.
    Tools needed:
    Jack, jackstands, socket wrench with extensions. Vice grip. Drill and a 2 1/8 hole saw.

    First: loosen up the lug nuts then jack up the car. Take off the tire and take off the lower bolt I believe itís a 17. You might need some PB blaster because some of these bolts can rust and it can be hard to take off. A few years back I bought brand new screws and bolts when I redid my front end. Take off the brake lines bolted to the shock. Take off the 14 from the bottom of the shock and take out the pitch fork. Then loosen up the top 3 bolts that hold the shock to the shock tower. Lower the shock with spring.
    On top you will have to bend in the 3 tabs with a vice grip.

    This is where you will need a drill with a 2 1/8th inch hole saw. You will need to drill the hole bigger because the Chedda top hats will not clear the stock hole size.
    Cutting bigger holes for top hat install - YouTube
    Im testing the fit and making sure the top hat fits.

    Had to drill out the holes on my dc strut bar because the holes are a bit small and would not fit on right.
    Had the konis set up on the lowest firmness and now that I took it out for a sprinted drive I had to adjust them to 75% firm.

    Car on the lowest setting. Took it out for a drive and it was way too low. My downpipe was not made for car this low.

    how low can you go?
    i can still go about 3/4 inch lower because of my front cut pitch fork and I can adjust the koni to the lower Perch

    Re: How To: Cheddasauto Front Top Hat Installation Guide

    Correct. You'll have to use spacers (washers) and longer bolts from the ef to make them work

    Re: How To: Cheddasauto Front Top Hat Installation Guide

    The longer bolts are to the shocks because there further apart the the stock 3geez. We didn't try other year's sleeves as these were made with special spring rate for the 3geez.

    Re: How To: Cheddasauto Front Top Hat Installation Guide

    Okay so I'm trying to confirm a parts list, and have a question about that last issue, the '97 Prelude bushings for the stock(?) top hat. Do you have a part number?

    So far I have this;

    These springs, with the Koni Sport (+$40) option
    Ground Control - Coilover Conversion kit, 86-89 Honda Accord

    The Koni Sport (Yellow, first option) Shocks for 88 Civic (Front and rear)
    Koni North America - ITT

    These Bushing kits
    Cart - Free Shipping on Orders Over $99 at Summit Racing

    And of course the Cheddas top hats (as well as the upper control arms)
    Web Store


    What else do I need? What are the '97 Prelude top hat bushings you mentioned? Thanks

    I used 88 civic ground controls to match the shocks. for the rear busshings i used 5th gen prelude stock replacement rear top hat busshing and it worked just fine. I did order shorter springs in the front 7 inch but you can get away with 8 or 9 inch spring if you want to preload your front spring. for the rear i used a 9 inch spring because the shock of the civic is way shorter than the stock accord one. Im lowered about 2.5-3 inch in the front and 2in in the rear.

    Hahaha man, always you and links haha.

    And oh wow, is that everything you need right there? Also I'd still want to use the top hats and UCA/LCA's, to prevent bottoming out shocks and to correct camber and what not. So still expensive but not as bad

    Re: How To: Cheddasauto Front Top Hat Installation Guide

    Everything I've read about them suggests that they are a all in one kit, with chamber adjustments built into the top of the shock. Next year (March or April) when I get my 15 year bonus from work I'll be able to tell you how they work.
