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 over’s 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 it’s 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.

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.
