DIY: GTSPEC 4-Point Ladder Brace

M.Bonanni · 05-05-2009, 05:40 PM

GTSPEC 4-Point Ladder Brace Install DIY by DoubleDownMotorsports.com

NOTE: The production ladder bars from GTSPEC are blue. This black version is just a prototype sent to us for test fitment purposes.

Estimated Install Time = 30 minutes
Difficulty = Easy

Tools Needed:
- Floor Jack
- Jack Stands
- Ratchet with 17mm socket
- 17mm wrench

Step #1:
Jack the rear of the car up until the rear tires are off the ground and you can slide jack stands underneath the frame rails. Repeat for front tires until all four corners of the car are safely on jack stands. Once jack stands are in place, slowly lower the car onto the jack stands and remove jack from work space. Double check to ensure that the jackstands are properly placed and all four corners of the stands are firmly planted on the floor. I even like to give the car a nudge or two to make sure it doesn't move at all or fall off the stands before I get underneath it.

Step #2:
Locate the bolts circled in the photo and remove them using the 17mm socket. This two front bolts are near the front of the car just behind the factory plastic under tray. The two bolts towards the rear of the car have a nut and a bolt. Use the 18mm wrench to hold the nut in place while you use the 17mm socket to un-screw the bolt.

Two bolts towards the front of the car...

Two bolts towards the rear of the car...

Step #3:
Line up the GTSPEC brace with the holes. Re-install the four bolts re-using the stock bolts toward the rear and the longer bolts provided by GTSPEC towards the front.

Step #4:
Thats it! Reverse Step #1 to get the car back on the ground and you are done!

Any weight spec on this piece? And any technical information regarding how it affects handling/stability of the car? I bought one of these for my 2000 Prelude way back in the day and don't remember what it's affect was.

I didn't weigh it, but I would guess it weighs 1-2 lbs. What it does is basically ties parts of the front sub-frame together and eliminates flex between them. The result is a sharper and better steering feel and turn-in and a little better handling. Its not really noticeable under normal driving to work & back, but I can tell that the front end is stiffer in some instances, like going over a speed bump at an angle where the subframe normally would flex a little. I haven't been to the track yet with this peice, but that is where the real effects should be felt.

Nice fit, quick install. Took about an hour. Was taking my time with putting the car up on stands. With a lift would take about 10 mins tops.
