It is well known these are by far the best front springs available for street (and track for your Datsun Roadster. Perfect height/stiffness compromise. Firm ride, but not harsh.
 
Unparalleled ride, stability and comfort when paired with Sport Touring or "Koni-Medium" calibrated Bilsteins.
 
These are absolutely the best spring for street and vintage racing-hands down.
 
See the combo deal for best pricing.  In stock for immediate shipping. 
 
Mike spent considerable time and money developing this outstanding spring and he’s a great guy as well!   Please support Mike's efforts by avoiding cheap, pirated, unlicensed copies!
 
Only the best from DRP.
