Over the last couple of days, I got the TL 20mm rear sway bar swapped over with moog end links, and I installed the coilovers.
Here are the TL sway bars, compared:
Lower bar is 2008 TL-S 20mm bar, upper is 2003 TL-S 19mm bar.
Despite only 1mm difference in diameter, the 20mm bar is WAY stiffer than the 19mm. No actual data, but when I stood them up next to each other and put my weight on one end, the 19mm bar flexed quite a bit. The 20mm bar had very little flex at all. I can't imagine that's all due to just the 1mm of extra thickness. I know the 20mm bar is solid, maybe the 19mm bar is hollow? Google isn't much help figuring that out and I don't want to cut up my 19mm bar to find out. Maybe the shape differences (19mm bar is more of a bow shape) contribute? not sure. all I know is that the new bar is a lot stiffer.
End links:
Probably don't need a note on which ones are on the car now...
Here's how I mounted the front coilovers so that the strut tower brace can bolt in:
No drilling necessary. All I did was bang out 2 of the strut tower brace studs in each of the coilover top hats with a hammer. The 3rd stud lines up perfectly with the hole in the Accord strut tower.
Here's how the car sits now:
First and probably only sticker I'll ever put on my car.
I didn't take measurements of before and after ride height, but I'd guess I've lowered the car 1.5" all around. I don't know how much lower I want it. I can mess with that after I get a chance to drive it for a while, but I kind of like it the way it is.
Driving notes:
To say that these parts transformed the car would be a wild understatement. The car has the same bones, same driving position, but it genuinely does not feel like the same car. The stock 15 year old suspension was clearly worn out, and it's sloppy to begin with. The higher spring rates and better damping were desperately needed. Car genuinely handles like it's on rails now. And that rear bar! it almost might be too much for the back end. I got rid of the rear spacers while I was at it so I've got 40mm more front than rear track right now. Once I go down to 5mm front spacers it may help to balance the car a bit more. It feels a hair oversteery, but the limits of the car are more than I can test on public roads, and I'm not exactly a rule follower when it comes to public roads either. That's how much it's improved. Body roll is straight up gone, and there is SO. MUCH. GRIP. Michelin super sports certainly don't hurt that cause.
I think I can also comment on the steering rack and engine changes now that I've put 30 miles or so on the car. The steering rack is heavier, but quite a bit quicker. I may need to bleed it some more, I may just need a new power steering pump, and I think axing those big front spacers will help the heaviness too. But the quickness is such a welcome change. Bigtime improvement.
I may have an exhaust leak that is contributing to lower torque below 3500 rpm, because the car actually feels more sluggish at low RPM. I may also have exceeded the capabilities of the stock j30 ecu with all the extra air I'm flowing. But once 4000rpm is crossed, the car absolutely screams. Definitely a vtech improvement with the new cams.
Lightweight flywheel is definitely an improvement, but a little more subtle than I thought it would be. It's easier to heel-toe for sure with the increased engine response, but it doesn't feel like a dramatic change. The car isn't great with heel-toeing anyway because of the pedal placement. I need to bring the gas pedal more in line with the brake pedal. Always more mods...
I've gone long with my descriptions, but to say I'm happy... yeah. I feel like the car is finally what I thought it could be.
