Extension Panel?

[Mustangcol]

So I changed the wheels and tires from 255/40r19 to FK510 285/35r19, 35psi. As expected, now the car has a little bit of tramlining on some roads with the wide tires. The suspension is solid bc I've done all the recommended mods (mods in signature) The car is a GT non-PP so it didnt come with strut tower brace or k-member brace. I found a good deal on the K-member brace and will give that a try. Earlier I had installed the strut tower brace from ford performance but didnt come with that extension panel to the firewall. I don't want to waste time and money shipping an extension panel to colombia if I don't need to. I'd rather spend the money on a steeda g-trac or something. Did you notice a difference adding that extension panel? I drive the car hard on mountain roads and don't feel anything weird, but if it's tramlining on dips in the road then I imagine the geometry is changing slightly and with some bracing, squeeze out a little more performance.

Some people say the extension does make a difference, for example:

its a big chunk of metal that fills in a void, i bet it does more than the strut tower brace itself. i did it all at once though and can't say how much difference it made versus just the braces.

I ordered the cowl extension on ebay. So the cowl extension and k-member brace should come at the same time.

Idk about adding more bracing like the 4-point brace. At least for now I am up to PP and GT350 spec with all the mods I've done. Minus the brakes. But ppl say good track pads plus fluid and the non-PP brakes are good enough

I got the cowl extension and PP1 k brace installed. I helped the mechanic and we did it in about 30 minutes. There is a significant reduction in tramlining so it was worth the effort. So I had 0 tramlining withe Falken FK520 255/40r19, switched to Falken FK510 285/35r19, tramlining appeared. Installed the braces and 90% of the tramlining is gone. I'm curious if the BMR 2-point brace would eliminate all the tramlining, but its not something on my priority list.
