Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.

The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.

For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.

Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

                      I will..still need alignment done and mount your 15" alloy rims & new tires (end of Oct. paycheck).

                      The exhaust on this car is very loud, need to take care of that too. I have to first find out where the holes are and I'm either going to temporarily fix the piping or just buy a header & get exhaust system made for it 2.25". We'll see.

                      Some cosmetic/functional things need to be taken care of. Replace side mirrors, front-driver bumper turn signal lens, new front hood/paint (deal with dad), I'd like to get a front lip for it, short shifter and/or adapter, install stereo system.

                        I just have to reinstall the rear seat, fix the front bumper turn & fog lights and clean the washer nozzles. Then, it's ready for winter driving and the white Accord is going to sit until spring.
                        Awesome. Will you be using white plates at each corner for the sedan?

                        Remember that POR-15 stuff you were talking about when I was up there way back when. I've got 3 start up kits here at work - FREE, distributor also started carrying it. Only problem is I dont have any rust to use them on. Guess I'll have to find something to use it on.


                          Thought this may interest people considering a Tokico HP Kit that's advertised as a 1.25" drop. I wanted this because I daily driver setup that's a bit better than stock. As you see the rear is more affected than the front.

                            Cisco, the daily driver is lookign great. Makes me want to get a CB7 again

                              1) The other 5 CB7s we have are all Akebono fronts and it makes it easier on me ordering parts, etc.

                              2) Hawk HPS pads are only offered for the Akebono fronts and down the line I will use them on this car as well (I have them on the white one already).
