While removing the temporary suspension from the DHC's body yesterday I used the opportunity and borrowed a compression strut kit, meant for a friend’s Mk2 Escort.
Needed them to trial fit under a TR7, as I still want to change ‘t Kreng’s front suspension to compression struts. Looks like a very straightforward upgrade for the front suspension. Only need to weld the two brackets to the front chassis legs and modify the joints for the TCA’s very slightly in the lath.
Some measurements showed that with my favoured ride-height for ‘t Kreng, the struts are still pointing slightly downward so should add some anti dive under braking.
Next challenge is to make some decent drop links for the anti-roll-bar!

I am interested in more information regarding the compression strut intallation. I am part of the team in the US and we are racing two TR7's in the 24hrs of Lemons series (endurance road racing). We are looking to improve the handing characteristics of the cars and think that adding a compression strut would help immensely. Can I ask if you know if more information is available regarding the installation of compression struts?
More info regarding our cars.....
pretty stock suspension with upgraded coil-over struts and higher durometer urethane rubber components. Still has sway bars installed. They tend to have some directional stability issues when doing hard braking from high speeds (100+ mph/160+kph). Stabilizing the lower control arm appears to be a good solution. Thanks in advance for your help
Hi Jeff,
Except for the info posted in this blog post I can’t add much more info. And that is becaiuse I still haven’t fitted the compression struts to his car.
Though around that time I did fit fully adjustable (custom made) front struts with much stiffer springs. These front springs are 60kg/cm (or 336lbs/in), giving an effective spring rate of 65,4kg/cm (366lbs/in). And this has seriously reduced dive under haevy braking.
Of course the rear springs were also changed to improve handling and balance. The rear springs are now 30kg/cm (168lbs/in). But as these are placed slightly behind the axle (and further away from the lower links body mounting point), the effective spring rate is 33.9 kg/cm (190lbs/in). Which is almost 45% higher compared to the original rear spring set up. So they compare to 43kg/cm (241lbs/in) springs in the original location.
