If you want a stiffer ride, I?d opt for adjustable dampers. An uprated stiffer spring might be too firm. If a rigid axle, stiffer springs potentially lead to evermore skittish back ends as well. Don?t ask how I know this. WareBe<br>

No surprise in the range of opinions you?ve received. Speaking for myself, I?ve owned and driven many TRs with beam axles ranging from new to fully restored and on the average British and European roads. After about two hours driving, the harshness of ride slowly became agonisingly painful and I had to stop. The cars are fun and I love them, but ride quality on sidescreeners and beam axled 4swas, imho, appalling. However, with IRS up the arse end, the ride was close to paradise for me, anyway. Hundreds will disagree.<br>
