If you own an MGC, you know that keeping its suspension in top shape is vital for both safety and driving enjoyment. The MGC, produced from 1967 to 1969, has unique suspension components compared to the MGB. Finding the right parts in California brings specific challenges—emissions laws don’t apply to suspension, but road conditions and local suppliers matter. This guide covers the key suspension parts you may need, what to look for when buying, and where to source them in California.
Understanding the MGC Suspension System
The MGC uses a front suspension with double wishbones and coil springs, while the rear has a live axle with semi-elliptic leaf springs and lever-arm dampers. Many owners upgrade to tube shocks for better handling. Key components include:
- Coil springs – front, often sag over time.
- Leaf springs – rear, can lose arch and cause a low ride.
- Shock absorbers – lever-arm (original) or tube-type conversion for improved damping.
- Bushings – rubber or polyurethane for the suspension arms, sway bar, and leaf spring eyes.
- Anti-roll bars – front and rear, some cars came without rear bars.
- Steering components – tie rod ends, idler arm, rack (if converted).
Why You Might Need New Suspension Parts
Common signs: excessive body roll, sagging on one side, bouncy ride, clunking noises, uneven tire wear, or poor steering response. California’s roads vary from smooth highways to potholed city streets, so quality parts matter.
Choosing the Right MGC Suspension Parts
Springs and Leaf Springs
Stock replacement coil springs are available from specialist suppliers. If you want a sportier ride, consider lowered springs (1–1.5 inch drop). For the rear, new leaf springs with standard or upgraded arch height improve stance. Ensure the spring rate matches your driving style and typical load.
Shock Absorbers
Original lever-arm dampers (Armstrong or Girling) are rebuildable but not ideal for performance. Many Californian owners convert to tube shocks using a conversion kit. Brands like Koni, Spax, or GAZ offer adjustable damping. This upgrade significantly improves handling. Check that the kit mounts are sturdy and don’t interfere with other components.
Bushings and Mounts
Rubber bushings deteriorate with age. Polyurethane bushings provide firmer feel but can increase road noise. For daily driving in California, quality rubber or hybrid materials (like SuperFlex) offer a good balance. Replace all bushings at once for consistent behavior.
Anti-Roll Bars
Adding or upgrading a rear anti-roll bar reduces body roll. Some MGCs came without one. Kits from companies like Moss Motors or Barney’s MG are available. Ensure proper brackets and hardware for California vehicles.
Considerations for California Roads and Climate
California’s climate causes rubber and plastic components to dry out faster. Choose parts made from UV-resistant materials where possible. If you drive in coastal areas, stainless steel hardware resists corrosion. For mountain roads, adjustable shocks let you dial in more damping for twisty sections.
Legal Compliance
Suspension modifications are generally legal in California as long as they do not raise or lower the vehicle beyond certain limits (typically 19 inches from ground to lowest part, but check local codes). Extreme lowering may cause issues with speed bumps or steep driveways. Aftermarket suspension does not require CARB approval (that applies to emissions). However, if you change ride height significantly, you may need a smog check referee inspection if a police officer questions legality. Stick to reasonable changes.
Where to Buy MGC Suspension Parts in California
Several specialty retailers in California stock MGC parts:
- Moss Motors (Goleta, CA) – large inventory of stock and performance suspension components.
- British Auto Parts (Sacramento, CA) – offers bushings, springs, and shock kits.
- Sports & Classics (San Jose, CA) – carries rebuild kits and aftermarket upgrades.
- Barney’s MGB & MGC (online, based in CA) – specializes in hard-to-find parts.
Additionally, local British car clubs (like the MG Car Club of Southern California) often have members selling used parts or can recommend trusted shops.
Online Ordering vs. Local Pickup
Ordering online from California-based suppliers ensures faster shipping and lower costs. Many offer free shipping over $100. If you need parts urgently, check for local inventory. Some shops allow will-call pickup.
Installation Tips and Common Pitfalls
- Alignment – After suspension work, get a professional alignment. MGC front suspension has limited adjustment; shims are needed for camber.
- Lever-arm to tube shock conversion – requires removing the original lever arm brackets. Follow kit instructions precisely to avoid interference with the steering rack.
- Leaf spring removal – use penetrating oil on U-bolts and shackle bolts beforehand; they often rust.
- Bushing pressing – polyurethane bushings sometimes need lubrication to avoid squeaking. Use the supplied grease.
If you’re not comfortable with DIY, many British car specialists in California (e.g., in Los Angeles, San Francisco, San Diego) perform suspension work.
Cost Breakdown
- Coil springs: $50–$150 per pair
- Leaf springs: $200–$400 per pair
- Tube shock conversion kit: $200–$500
- Shocks (pair): $100–$400
- Bushing set (full poly): $100–$200
- Anti-roll bar kit: $200–$400
Labor if hiring a shop: $500–$1,200 for full suspension overhaul.
Final Recommendation
For most MGC owners in California, start with replacing all bushings and worn shocks. If you want improved handling, invest in a tube shock conversion and a rear anti-roll bar. Stick with reputable brands from California-based suppliers to avoid counterfeit parts. If you’re on a budget, focus on essentials like springs and bushings. Always prioritize safety—if you notice play in steering or suspension, address it promptly. Join a local MG club for advice and potential discounts.
With the right parts, your MGC will handle California’s diverse roads with confidence.
