Toyota MR2 SW20 Street coilover suspension D2 TÜV approved 3sge 3sgte

Toyota MR2 MK2 (SW20), the D2 Racing Street (RS Series) coilovers are a popular choice for balancing daily drivability with occasional track performance. They are compatible with both the naturally aspirated (3S-GE/5S-FE) and turbocharged (3S-GTE) models.

Technical Specifications

Part Number: D-TO-43 (for SW20 1989–1999 models).
Damping: 36-way adjustable (monotube design) for fine-tuning rebound and compression simultaneously.
Spring Rates:
- Front: 3.8 kgf/mm
- Rear: 6.7 kgf/mm
Adjustability: Independent ride height and spring preload adjustment, allowing you to lower the car without sacrificing shock travel.
Top Mounts: Usually includes pillowball top mounts with rubber vulcanization to reduce road noise while providing camber adjustment for the front struts.

TÜV & Compliance

D2 Racing is an ISO 9001 certified manufacturer. Many European distributors supply these kits with TÜV Austria or TÜV Rheinland certificates, making them legal for road use in countries with strict inspection requirements (like Germany or Austria).

Verification Tip: If you are purchasing this specifically for a road-legal build in the EU, ensure the vendor explicitly includes the TÜV Gutachten (certificate) in the box, as some “grey market” or US-spec versions of the same kit may not include the paperwork required for your local registration office.

Installation & MR2 Specifics

Sway Bar Links: On the SW20, the front sway bar attaches directly to the strut. Ensure the kit includes the welded brackets for the end links (standard on the D-TO-43 kit).
Brake Line Brackets: The kit features OEM-style brackets for the brake hoses, eliminating the need for zip ties or custom fabrication.
Corrosion Resistance: The shock bodies are typically teflon-coated or anodized 6061 aluminum, which is beneficial for street cars exposed to road salt and winter conditions.

Comparison: Street vs. Sport

If you find the Street series too soft for heavy track use, D2 also offers the Sport Series for the SW20. The Sport version is approximately 30% stiffer (roughly 4.5kg Front / 7.5kg Rear) and sacrifices some low-speed comfort for better high-speed stability
