In the past I have posted here telling about the TCI 67-69 Camaro IFS subframe and have gotten blasted as it being a glorified street rod suspension. Recently TCI competed at the Super Chevy Magazine Suspension and Handling Challenge. Mary Pozzi drove all the cars in the autocross so it made the competition as fair as possible.
TCI's 68 Camaro had their Coilover IFS subframe under the front and their new Torque-arm rear suspension in the rear and included their subframe connectors to tie the front and rear together. The front and rear both had TCI's own billet double adjustable coilovers. They were running Michelin PS Sport II tires with a 200 tread wear rating. The size was 275/35R18 on the front and 315/30R18 on the rear. This all fits under the car with out major rear subframe modifications. They beat everyone in the autocross and came in 2nd in the slalom. Here is a link to TCI's website showing the 5 autocross runs the Mary made in the car.

At the end it shows the times. Every run she picked up almost 1 second. The current Super Chevy issue shows 2 of the competitors and the next 4 issues will show the results of all 10 cars that competed.
TCI showed everyone that they have developed a great suspension system that works.
