More than likely, tuning, driving, and experience. I didn't bother looking at the links, but I saw English Racing and RRE, and I would expect great cars from both companies.
I agree totally. But these aren't really that modded or stripped cars either.

car specs
The full weight English Racing Galant goes 12.2@114.9 on a Big 16G and pump gas.
English Racing purchased a Mitsubishi Galant GVR4 a few months back for the new family car to replace the Wife's 92 TSI (The Sportcake). The only mod the car had done to it was our GVR4 FMIC kit that we did as a prototype. Last week the car got some more mods...here is the list of what we have done to it.
* English Racing FMIC kit with intake (core 25Ă—10x2-7/8)
* MAFT with 3in meter
* 255 hp fuel pump
* English Racing Methonal kit
* Big 16g with 2g exhaust manifold
* English Racing 3in turbo back exhaust (Mandral bent)
* Boost and methonal pressure gauges
* 4 bolt rear with the AWS stearing removed.
* ACT 2600 with street disc and ACT streetlite flywheel
* English Racing Boost controller set to 25psi.

I've seen people with twice the mods and a 35r not hit this time or this one:
The English Racing red 92 tsi which is Lucas English wife's car named the sport cake turns a new best in the 1/4mi. Still on the stock 14b, 450cc and pressure plate turns an amazing 12.3@110 with full weight and a towing hitch for the jet skies.
