So the idea that the torsion bar suspension will cost just as much to modernize is BS, you can do suspension for the entire car and still be almost a thousand bucks ahead compared to just the AlterKation in the front.
You are being disingenuous by adding the cost of the Street Lynx rear suspension in with the cost of the Alter-k-tion to compare it to you deflated prices in your parts prices.
The cost of an apples to apples / OE type suspension to Alter-K-tion is a difference of hundreds.
